CIDEX® OPA Solution Test Strips
Test Strips for ortho-Phthalaldehyde (OPA) in CIDEX® OPA Solution
Chemical Sterilization Process Indicator
Cidex® Solution Test Strips (K915170)
DESCRIPTION OF THE CIDEX® OPA SOLUTION TEST STRIP
(2'2ý / ý a_
The CIDEX® OPA Solution Test Strips consist of a 0.2 x 0.2-inch reagent-containing pad attached to one end of a 0.2 x 3.25-inch polystyrene handle. The indicator pad contains a
color-forming reagent. It also contains an inhibiting compound that prevents visible reaction when the OPA concentration is at or below the MEC. When the OPA level is in sufficient excess of the MEC, the surplus reacts with the color-forming reagent.
The sample is placed in a 12 x 75-mm glass test tube. The indicator pad is immersed in the sample for 30 seconds, removed and allowed to react for an additional two and one-half

minutes at which time it is compared to a color standard. If the color of the entire pad is
equal to or darker than the color standard, the concentration of ortho-phthalaldehyde (OPA) in CIDEX@ OPA Solution is above the minimum effective concentration (MEC). If any part
of the pad is lighter than the color standard, the CIDEX© OPA Solution should not be used.
INTENDED USE
CIDEX@ OPA Solution Test Strips are semi-quantitative chemical indicators used to
determine whether the concentration of OPA in CIDEX@ OPA Solution is above or below
the MEC. CIDEX© OPA Solution Test Strips cannot be used to validate the disinfection
process.
TECHNOLOGICAL COMPARISON TO THE PREDICATE DEVICE
CIDEX@ OPA Solution Test Strips are used for determining OPA in CIDEX@ OPA
Solution whereas the CIDEX@ Solution Test Strips are used for determining glutaraldehyde
levels in CIDEX© Activated Dialdehyde Solution. Both tests have dry, reagent-containing paper indicator pads attached to plastic handles. Both pads contain an inhibitor that prevents
reaction with an indicator at ineffective active ingredient concentrations.
The reaction pad of the CIDEX@ OPA Solution Test Strips is observed three minutes after
the strip is immersed in the solution while that of CIDEX@ Solution Test Strips is read between five and eight minutes after immersion. For interpretation of the result, the indicator
pad of the CIDEX® OPA Solution Test Strip is compared with a standard color block. The
CIDEX® Solution Test Strips use a visual standard for interpretation of the result.
STATEMENT OF SUBSTANTIAL EQUIVALENCE
Eight individuals used CIDEX@ OPA Solution Test Strips from three trial production lots in
blind studies to test CIDEX@ OPA Solution standards. Three of the readers were inexperienced in laboratory techniques. A total of 324 results were obtained with each standard.
At the MEC (0.30% OPA), 324 results were FAIL giving a specificity (lack of false PASS
results) of 1.00. At 0.40% and 0.45% OPA, 322 and 324 results, respectively, were PASS.
These results show that the CIDEX@ OPA Solution Test Strips effectively indicate when the
OPA concentration in CIDEX® OPA Solution is at the MEC of 0.3%.

NARRATIVE DEVICE DESCRIPTION
1. INTENDED USE: The CidexTM OPA Solution Test Strip is intended for monitoring the concentration of ortho-phthalaldehyde (OPA) in germicide solutions with a minimum effective concentration of 0.3% OPA. The indicator is dedicated for use with CidexTM OPA Solution.
2. DEVICE DESCRIPTION: The CidexTM OPA Solution Test Strips are chemical indicators used for determining whether the concentration of OPA in CidexTM OPA Solution is above or below the minimum effective concentration of 0.3%. The indicator pad measures 0.2 inches x 0.2 inches and is attached to a 0.2 inch x 3.25 inch polystyrene handle. The strips are packaged in groups of 60 strips with a desiccant pack in containers made of HDPE. One 12x75 mm glass test tube is supplied with each bottle. The cap is made of HDPE with a cap liner consisting of pulpboard backing covered with vinyl coated aluminum foil. The formula is shown in Table 1.
Table 1. Formulation of the Strips ingredients % by Weight
Sodium sulfite 32.2 Ammonium citrate 46.6 Gantrez 21.2 TOTAL 100%
_ Chemical principle: The OPA reacts with sodium sulfite to form an addition compound. The excess OPA then reacts with ammonium ions to form colored polymers. When the OPA concentration is 0.3% or less, it is entirely consumed with the sodium sulfite to produce colorless product. When its concentration is sufficient to overwhelm the sodium sulfite, the excess reacts with ammonium ions to produce colored polymers (brown/black). If the solution contains 0.3% OPA or less, the pad will be lighter than the color block on the package and should indicate FAIL. If the solution contains 0.45% OPA or more, the pad color will be equal to or darker than the color block and should indicate PASS. At intermediate concentrations of OPA, the test strip may indicate either PASS or FAIL.
A 12x75 glass test tube is provided with the strips for use in testing samples of CidexTM OPA solutions. About 1 ml of CidexTM OPA solution is placed in the glass test tube. After immersing the strip in the CidexTM OPA solution for exactly 30 seconds, the test strip is removed by touching the side edge of the pad against the inside of the tube and is drawn upward for 2-3 seconds against the entire length of the test tube. The handle end of the strip is laid on a paper towel so that the indicator pad hangs over the edge to prevent further absorption. After 2.5 minutes following removal of the strip from the solution, the color of the indicator pad is compared to the color block on the container.

Chemical principle: The OPA reacts with sodium sulfite to form an addition compound. The
excess OPA then reacts with ammonium ions to form colored polymers. When the OPA concentration is 0.3% or less, it is entirely consumed with the sodium sulfite to produce colorless
product. When its concentration is sufficient to overwhelm the sodium sulfite, the excess reacts
with ammonium ions to produce colored polymers (brown/black). If the solution contains 0.3%
OPA or less, the pad will be lighter than the color block on the package and should indicate
FAIL. If the solution contains 0.45% OPA or more, the pad color will be equal to or darker than
the color block and should indicate PASS. At intermediate concentrations of OPA, the test strip
may indicate either PASS or FAIL.
A 12x75 glass test tube is provided with the strips for use in testing samples of CidexTM OPA
solutions. About 1 ml of CidexTM OPA solution is placed in the glass test tube. After immersing the strip in the CidexTM OPA solution for exactly 30 seconds, the test strip is removed by

These revisions are adequate to emphasize to the user the need to practice the technique before using the strips.
2. The firm revised the labeling as follows to reflect the test tube rinsing procedure used in the test tube reuse study:
These directions do not agree with the process used in the test tube reuse study conducted by the firm. In the study, the firm demonstrated that rinsing the tube once with Enzol and then rinsing three times with tap water followed by rinsing three times with deionized water was adequate for at least 70 uses of the tube.
3. The firm indicated that because users do not use the strip as frequently as recommended by the manufacturer, the firm does not expect users to follow a recommendation to use three strips instead of one. The firm noted that the technique is similar to that used for the Bayer urine test strips and is considered a "Low Complexity" procedure under CLIA and thus is CLIA waived. The firm noted that because the directions for the reuse of the solution are to test the MEC before each use, the chance of a strip not showing fail in the last three days is
-- extremely small. The firm also provided a statistical evaluation of the data and included the

article, "Assessing pass/fail testing when there are no failures to assess,"' by Thom R.
- Nichols and Sheldon Dummer along with expanded statistical tables. I asked Pamela Scott, OSB, to review the statistical information.
I discussed my concerns about this product with Dr. Chiu Lin. I noted that out of 6 lots of strips tested by the firm, 1 lot showed 2 false pass results and that the results are very technique sensitive. The firm beefed up the labeling recommending that the user practice using the strips before starting use of the strips. He indicated that he would have more confidence in the strip if the firm conducted additional testing of about 20 strips from 1 lot with Cidex OPA solution
containing 0.2% OPA. I phoned Dr. Christner on 1115199 to request the following information:
I requested that he send the information via fax followed by a hard copy to DMC.

From: Scott, Pamela E Sent: Friday, November 12, 1999 9:53 AM To: Mayhall, Elaine Cc: Lin, Chiu S.; Ulatowski, Tim; Barrick, Mary K.; Stein, Bridgette R.; Scott, Pamela E Subject: Statistical review of sponsor's response to ODE's questions about K992341 Cidex
OPA Solution Test Strips, Serim Research Corp.
Introduction The sponsor states that the OPA Solution Test Strips are semi-quantitative chemical indicators used to determine whether the concentration of OPA, the active ingredient in the solution, is above the minimum effective concentration (MEC) of 0.3% OPA. The "color" developed on the Cidex OPA Solution Test Indicator Pad determines whether the concentration of OPA in the sample is above or below the minimum effective dose of 0.3%. If the "color" of the indicator pad is equal to or darker than the gray color block on the bottle label, then the solution is considered to "pass" and the concentration is above the MEC of 0.3% OPA. If the "color" of the indicator pad is lighter than the "color" block on the solution bottle label, then the solution is considered to "fail"
and the concentration is at or below the MEC of 0.3% OPA and should be discarded.
Since the Division of Biostatistics did not perform a review of the original submission, my review is limited to the sponsor's response to your 101811999 phone call. As a result, additional statistical issues may arise from a statistical review of the original submission.

r CIDEX®OPA Solution Test Strips are semi-quantitative chemical indicators used to indicate whether the concentration of ortho-phthalaldehyde, the active ingredient in CIDEX® OPA
Solution, is above the minimum effective concentration (MEC) of 0.3% OPA. It is recommended that CIDEX®OPA Solutions be tested before each usage with CIDEX® OPA Solution Test Strips.
WARNING: CIDEX® OPA Solution Test Strips cannot be used to validate the disinfection process. Do not use CIDEX® OPA Solutions beyond the 14-day maximum use life even if the test strip shows the solution is above the MEC.
The filter paper square (indicator pad) mounted on the end of plastic strip comprises the reactive portion of the CIDEX® OPA Solution Test Strip. The indicator pad contains an inhibitor and a
color-forming reagent. If the concentration of OPA is at or below the MEC, the inhibitor will prevent any color formation. If the concentration of OPA is present in excess of the inhibitor, it reacts with the color-forming reagent to form colored pigments.
" CIDEX®OPA Solution Test Strips must be kept in the original bottle with the cap tightly closed.
" Store in a dry place at controlled room temperature; 16°-32° C (61°-90° F).
" Protect strips from exposure to extremes of heat, light and moisture.
" Do not remove the desiccant pack. Keep desiccant out of reach of children.
" Use within 90 days after first opening the bottle.
" Always write the "Date Opened" in the space provided on the bottle label.
" Do not use test strips (from an opened or unopened bottle) after the expiration date.
IMPORTANT: Prior to starting routine use of the CIDEX® OPA Solution Test Strips, it is advisable to practice the testing technique using control solutions (the preparation of which is described in the "QUALITY CONTROL" section). Familiarity with the proper testing technique will increase user proficiency, minimize procedural errors and assist in interpretation of results.
Sample Collection
Collect approximately 1 mL of room temperature CIDEX® OPA Solution into the 12x75-mm glass test tube provided. The tube should be approximately 1/5 full allowing the indicator pad on the test strip to be fully immersed in the sample.

Testing Procedure
Dispense approximately 1-mL of CIDEX® OPA Solution into the 12x75-mm glass test tube
provided.
2. Dip the test strip into the sample for exactly 30 seconds.
3. Remove the test strip by touching the side edge of the indicator pad against the inside of the test tube and draw upward (for approximately 2-3 seconds) against the entire length of the
test tube, gradually removing excess sample. (See Figure 1.)
Figure 1
4. Lay the handle end of the test strip on a paper towel so that the indicator pad hangs over the edge of the towel to prevent absorption of the sample solution.
5. Compare the color of the indicator pad to the color block on the bottle label at exactly 3 minutes after the test was started (2'/z minutes after removing the strip from the test tube.)
6. Use the logbook in CIDEX® Solutions Information Station (Reorder No. 20251) to record results.
7. Discard the test strip and CIDEX" OPA Solution test sample in accordance with federal, state, local and institution guidelines.
8. Clean the test tube with Enzol® or an equivalent detergent, then rinse the test tube thoroughly with three changes of tap water followed by three distilled water rinses. Dry completely prior to next use.
INTERMFTATIONOFTM RESULTS
The color developed on the CIDEX®OPA Solution Test Strip Indicator Pad is used to determine whether the concentration of OPA in the sample is above or below the MEC of 0.3%.
" For a "PASS", the entire indicator pad should be equal to or darker than the gray color block on the bottle label.
" If the entire indicator pad is lighter than the color block on the label or distinct areas of lighter color are observed, the result is a "FAIL". The CIDER®OPA Solution is at or below the

At concentrations slightly above the MEC the indicator pad may have a mottled appearance.
However, if any portion of the indicator pad is lighter than the color block, the results should be considered a "FAIL".
NOTE: False "FAILS" may occur as the MEC is approached. This is due in part to a safety
margin provided by the test strip ensuring that solutions at or below the MEC Will

Testing Freauencv
Each facility should determine the frequency of control testing for its own QC program. All personnel responsible for monitoring disinfectants should practice testing the positive and negative controls prior to starting routine use of CIDEX OPA Solution. Regular testing of the control solutions will increase user proficiency, minimize procedural errors and protect against the inadvertent use of outdated product or product that has deteriorated due to improper storage or handling.
Preparation and Testing of Control Solutions
Verify that the CIDEX® OPA Solution has an acceptable expiration date. Label two tubes, one for the positive control and one for the negative control. To prepare a positive control use fresh, full strength solution. To prepare a negative control, dilute one part of full strength solution with one part of distilled water. Following the "Directions for Use", dip one test strip in the positive control and one in the negative control.
Results for Control Solutions:
Refer to the color block on the test strip bottle for interpretation of results.
" At 3 minutes, the test strip dipped in the full strength positive control solution should exhibit a completely gray/black color on the indicator pad equal to or darker than the color block on the bottle label indicating a PASS result.
" The test strip dipped in the negative control should show a color lighter than the color block on the bottle label when read at 3 minutes indicating a FAIL, result.
If the results obtained from using the positive and negative controls indicate the test strip is not
performing as expected, do not use the remaining strips, but retain them for possible return to Product Quality Services. For technical product information and support, contact Advanced Sterilization Products at 1-888-783-7723.

The "Directions for Use" MUST be followed closely to achieve optimal test results. Outlined below is an explanation of the significance of the technique for each step in the Test Procedure. This information may be useful for training and troubleshooting.
" Leaving the test strip in the sample of CIDEX® OPA Solution for longer than 30 seconds or
swirling the strip vigorously could cause excess color development. This could lead to a false "PASS"
result, i.e., the concentration of OPA in the solution is truly below the MEC, but due to improper technique the test strip gives a "PASS" result.
" Removing the test strip too soon from the solution or blotting the indicator pad with an absorbent material such as a paper towel could cause insufficient color development. This could cause a false "FAIL" result when the solution would normally pass.
" It is important to use the 12x75-mm glass test tube provided. The procedure and timing were optimized using this specific test tube
" Failure to draw the side edge of the indicator pad slowly (for 2-3 seconds) up the inside of the test tube could lead to a false "PASS" due to retention of excess sample.
" Thoroughly clean, rinse and dry the test tube between each use. For optimal results, use a new test tube with each new bottle of strips.
" Although excess sample solution must be allowed to drain from the indicator pad, it is important not to remove too much solution. Therefore it is recommended that once the test
strip is removed from the test tube, the indicator pad should not come in contact with an absorbent surface. The test tube wall removes the proper amount of sample as opposed to paper towels, which have a tendency to absorb an excessive amount of solution from the indicator pad. The use of this test tube/sample removal technique provides significantly improved and consistent results when compared to alternate sample removal methods used with other tests
(i.e., blotting or shaking excess liquid from the indicator pad.
" It is important to interpret the results of the test strip exactly 3 minutes after starting the test
(dip for 30 seconds, then allow reaction to develop for an additional 20 minutes).
" If the test is read in less than 3 minutes, the color change may be incomplete and a solution could give a false "FAIL" result.
" If the test is read after 3 minutes, excess color may develop and the solution could yield a false "PASS" result.
" The test strip may take on a mottled appearance as it approaches the MEC. Appearance of distinct areas of color lighter than the color block is considered a "FAIL" result.
" Only one test strip per one mL of sample may be dipped. If the test is repeated, 1 mL of fresh sample is required.

CB)EX0 OPA Solution Test Strips are semi-quantitative chemical indicators used to indicate.
whether the concentration of ortho-phthalaldehyde, the active ingredient in CmEX°° OPA Solution, is above the minimum effective concentration (MEC) of 0.3% OPA. It is recommended that CIDEX* OPA Solutions be tested befqre each usage with CIDEX* OPA Solution Test Strips. WARNING: CIDEX°
OPA Solution Test Strips cannot be used to validate the disinfection process. Do not use CIDEX* OPA Solutions beyond the 14-day maximum use life even if the test strip shows the solution is above the 1VIEC.
The filter paper square (indicator pad) mounted on the end of plastic strip comprises the reactive portion of the CmEX® OPA Solution Test Strip. The indicator pad contains an inhibitor and a color-forming reagent. If the concentration of OPA is at or below the NEC, the inhibitor will prevent any color formation, If the concentration of OPA is present in excess of the inhibitor, it reacts with the color-forming reagent to form colored pigments.
" .CmEX® OPA Solution Test Strips must be kept in the original bottle with the cap tightly
closed. " Store in a dry place at controlled room temperature; 16°-32° C (61°-90° F). " Protect strips from exposure to extremes of heat, light and moisture. " Do not remove the desiccant pock. Keep desiccant out of reach of children. " Use within 90 days after first opening the bottle. " Always write the `Date Opened" in the space provided on the bottle label. " Do not use test strips (from ati opened or unopened bottle) after the expiration date.
7405M" I-Rk INN EWORTANT: Prior to starting routine use of the CmWO OPA Solution Test Strips, it is advisable to practice the testing technique using control solutions (the preparation of which is described in the "QUALITY CONTROL" section). Familiarity with the proper testing technique will increase user proficiency, minimize procedural errors and assist in interpretation of results.
Sample Collection
Cdllect approximately 1 mL of room temperature CIDEX* OPA Solution into the 12x75-mm glass test tube provided. The tube should be approximately 1/5 full allowing the indicator pad on the test strip to be fully immersed in the sample.

At concentrations slightly above the MEC the indicator pad may have a mottled appearance. However, if any portion of the indicator pad is lighter than the color block, the results should be considered a'TAIL".

Each facility should determine the frequency of control testing for its own QC program. All personnel responsible for monitoring disinfectants should practice testing the positive and negative controls prior to starting routine use of CMEX OPA Solution. Regular testing of the control solutions will increase user proficiency, minimize procedural errors and protect against the inadvertent use of outdated product or product that has deteriorated due to improper storage or handling.
Preparation and Testing of Control Solutions
Verify that the CIDEX® OPA Solution has an acceptable expiration date. Label two tubes, one for the positive control and one for the negative control. To prepare a positive control use fresh, full strength solution. To prepare a negative control, dilute one part of full strength solution with one part of distilled water. Following the "Directions for Use", dip one test strip in the positive control and one in the negative control.
Refer to the color block on the teat strip bottle for interpretation of results. `
" At 3 minutes, the test strip dipped in the full strength positive control solution should exhibit a completely gray/black color on the indicator pad equal to or darker than the color block on the bottle label indicating a PASS result.
" The test strip dipped in the negative control should show a color lighter than the color block on the bottle label when read at 3 minutes indicating a FAIL, result.
If the results obtained from using the positive and negative controls indicate the test strip is not performing as expected, do not use the remaining strips, but retain them for possible return to Product Quality Services.

The "Directions for Use" MUST be followed closely to achieve optimal test results. Outlined below is an explanation of the significance of the technique for each step in the Test Procedure. This information may be useful for training and troubleshooting.
" Leaving the test strip in the sample of CIDEX& OPA Solution for longer than 30 seconds or swirling the strip vigorously could cause excess color development. This could lead to a false '?ASS"
result, i.e., the concentration of OPA in the solution is truly below the NIEC, but due to improper technique the test strip gives a "PASS" result.
" Removing the test strip too soon from the solution or blotting the indicator pad with an absorbent material such as a paper towel could cause insufficient color development. This could cause a false "FAIL" result when the solution would normally pass,
" It is important to use the 12x75-mm glass test tube provided. The procedure and tinning were optimized using this specific test tube
'
" Failure to draw the side edge of the indicator pad slowly (for 2-3 seconds) up the inside of the test tube could lead to a false '?ASS" due to retention of excess sample.
" Thoroughly clean, rinse and dry the test tube between each use. For optimal results, use a new test tube with each new bottle of strips.
- " Although excess sample solution must be allowed to drain from the indicator pad, it is important not to remove too much solution. Therefore it is recommended that once the test strip is removed from the test tube, the indicator pad should not come in contact with an absorbent surface. The test tube wall removes the proper amount of sample as opposed to paper towels, which have a tendency to absorb an excessive amount of solution from the indicator pad. The use of this test tube/sample removal technique provides significantly improved and consistent results when compared to alternate sample removal methods used with other tests (i.e., blotting or shaking excess liquid from the indicator pad.
" It is important to interpret the results of the test strip exactly 3 minutes after starting the test (dip for 30 seconds, then allow reaction to develop for an additional 20 minutes).
" If the test is read in I!Rlg 2sq; 3 njnte¢, the color change may be incomplete and a solution could give a false "FAIL" result.
" If the test is read after 3 minutes, excess color my develop and the solution could yield a false "PASS" result.
" The test strip may take on a mottled appearance as it approaches the MEC. Appearance of 'diets ct'n areas of color lighter than the color block is considered a "FAIL" result.
" Only one test stripper one rnL of sample maybe dipped. If the testis repeated, 1 tnL of fresh sample is required.

There is a tendency to forget that even if 10 components were
tested without failure, we still can't be absolutely sure how the
I 1 th would have performed. The resulting overoptimism could
"sult in the inclusion of a component in a product, or the
intro--auction of a product into the marketplace, that fails to perform
as expected.
A false sense of security is a particular danger when the
in-vestigator has not thought about the relationship between risk and
sample size. As an example, more risk is involved in stating that
a product is acceptable if we sample 10 with no failure from
a population than if we sample 500 with no failure from the
same population. This is because we derive more information
about the population from testing a sample of 500 than from
testing a sample of 10. It is more important to know that zero
fail-ure occurs in a sample size n than simply that zero failure occurs.
When no failures are found after a particular round of pass/fail
testing, the estimated failure rate is zero-if that single test is
looked at in isolation. What is often misunderstood in pass/fail
testing is that a zero failure rate for the given sample tested does
not ensure that the failure rate for the entire product or
compo-nent population is zero. When no failures are reported during sample testing, the natural tendency is for researchers to overlook
the maximum failure rate that could occur for the population as
a whole. The maximum failure rate for the population, not the
sample, must be understood, and should be part of the risk
as-sessment involved in decision making.
SAMPLE SIZE
What is an appropriate sample size for pass/fail testing? It
de-mends on how critical the product or component being tested is,
and how much risk the investigator (scientist, engineer, project
manager, decision maker) is willing to accept when deciding

whether or not to accept that product or component for
manu-facture or distribution. For any given sample size, with zero failures observed, there
is an ascribed confidence interval--worked out and tabulated by statisticians-in which the true failure rate will be found.'
Shown in graph form in Figures 1 and 2 are the upper bounds for
that failure rate, based upon 90 and 95% confidence intervals
(otl2). The advantage to presenting this information in
graph-ic form is that a knowledge of statistical theory is not required
to interpret it. , Figure 1 shows the upper limits at 90 and 95% confidence
in-tervals for failure rate when zero failures are observed. It is clear
from the graph that the fact that no failures are observed does not
mean that no failures are to be expected in the total population
of parts or components: rather, failure may be expected to be as
great as that defined by the curves. The graph can be
interpret-ed in several ways by considering the following scenarios.
Example 1. You have just completed a test in which 40
sam-ples were evaluated and you observed 0 failures. From Figure 1, the upper bound for the true failure rate is 8.8%. One can then state that, with 95°lc confidence, the true failure rate will be
con-tained in an interval not to exceed 8.8% failure. Example 2. You are required to make a decision about
con-tinuing with the development of a product line. Because of time
and cost limitations, the decision involves considerable risk. You decide to proceed with development if pass/fail testing indicates
a 90% chance that the true failure interval does not exceed a 3% failure rate. How many samples are needed with 0 failures

ex-pected failure when zero or one occurrence of failure is observed
during testing.
_CONCLUSION
Statistical analysis shows that in both attributes and variables
testing, as the amount of valid information increases, the asso-ciated risk in making a decision based on that information
de-creases. In pass/fail testing this means that the ability to estimate
with confidence the upper bounds of the true failure rate when
the observed failure rate is zero is critically dependent upon
sample size. Thus, decision making is also critically dependent
on sample size.

observed? The answer is 100, found by following the 90% confidence limit curve downward until it crosses the 3%
prob-ability line. The point of intersection corresponds to 100 on the sample axis.
Example 3. A sample size of 150 is tested with 0 failures ob-served. From the graph you find that there is a 95% chance that
true failure will occur within an interval bounded by an upper limit of 2.4% failure. The question you must ask yourself is this: Am I willing to proceed knowing that I have a 95% chance of product failure that could be as great as 2.-1%? In other words, does this risk analysis represent sufficient information about the product under development?
The colors of the graphs range from red (danger) to yellow (proceed with caution). If you are pass/fail sampling and
ob-serve zero failures from a sample of size n during the test. you should determine where on the confidence limit curves your upper range of failure exists. To do this, locate on the x-axis the number of samples you have tested, then move vertically until you cross either the 90 or 95% confidence curve. The color area you are in will give you a subjective determination of the risk of failure if you proceed with the development of this product (with red equaling higher risk and yellow equaling caution, or lower risk). You may then locate along the y-axis the upper
probabili-ty of failure occurring when all that you know about this prod-uct is that zero failures occurred in your sample size. Notice
that the graphs do not contain the color green (go). This is be-

TABLES OF EXPECTED PROBABILITY OF FAILURE
The following tables present the expected probability of failure when a failure is observed within a sample of size n. The probabilities are based upon the upper 5 percent, 2.5 percent, and 1 percent confidence intervals. As an example, if one wanted to know the upper limit percentage of failure that
could be expected when 3 failures were detected from a sample of size 20, at the 95 percent confidence interval, the table would indicate 37.9 percent. This is found by intersecting the upper 2.5 percent column with the sample
size=20, failure=3 row. The condition under which the distribution of failure probabilities are calculated is that the only information available to the investigator is that of pass/fail, or accept/reject status. In other words, such information as mode of failure, or time to failure, are not a criteria.
The expected probabilities of failure are exact probabilities and are based on the following equation which is a modification of that given by Collett'.
Pf - 1 -PL , where Pi - y[y+(n-y+1)F2(n-y.,), 2y
(a/2))"1
In the above equation Pf is the probability of failure, a is the sample size, and y is the observed number of non-failures. The value F is taken from the F distribution with numerator and denominator degrees of freedom given as
2(n-y+l) and 2y respectively.

MEMORANDUM
DATE: October 8, 1999
FROM: Elaine Schalk Mayhall, Ph.D., Chemist, Infection Control Devices Branch, DDIGD, HFZ-480
SUBJECT: K992341 SERIM RESEARCH CORP. CIDEXTM OPA SOLUTION TEST STRIP
CONTACT: James Christner 219-264-3440 (IN) 219-266-6222 fax
TO: The Record
Intended Use
The CidexTM OPA Solution Test Strips are semi-quantitative chemical indicators used to
determine whether the concentration of ortho-phthalaldehyde in CidexTM OPA Solution is above
or below the minimum effective concentration of 0.3%.
Background
Serim Research previously has submitted the following three 510(k)s for this product:
K972739 -withdrawn by the firm in a letter dated 914197 because the 510(k) for CidexTM OPA
Solution had been deleted.
K983290 - withdrawn and deleted from the system by FDA because the submission for
CidexTM OPA Solution had significant deficiencies that could not be resolved within 30 days
(letter dated 10198).
K983806 - withdrawn and deleted from the system by FDA because the submission for Cidex OPA Solution was deleted (letter dated 198); A list of our concerns about the indicator was sent to the firm via fax on 1218198.
Device Description
The CidexTM OPA Solution Test Strips are chemical indicators used for determining whether the
concentration of OPA in CidexTM OPA Solution is above or below the minimum effective concentration of 0.3%. The indicator pad measures 0.2 inches x 0.2 inches and is attached to a 0.2 inch x 3.25 inch polystyrene handle. The strips are packaged in groups of 60 strips with a desiccant pack in containers made of HDPE. One 12x75 mm glass test tube is supplied with each bottle. The cap is made of HDPE with a cap liner consisting of pulpboard backing covered with vinyl coated aluminum foil. The formula is shown in Table 1. The firm did not identify

"Gantrez" any further.
Table 1. Formulation of the Strips Ingredients % by Weight
Sodium sulfite Ammonium citrate Gantrez TOTAL 100%
Page 2
Chemical principle: The OPA reacts with sodium sulfite to form an addition compound. The excess OPA then reacts with ammonium ions to form colored polymers. When the OPA concentration is 0.3% or less, it is entirely consumed with the sodium sulfite to produce colorless product. When its concentration is sufficient to overwhelm the sodium sulfite, the excess reacts with ammonium ions to produce colored polymers (brown/black). If the solution contains 0.3% OPA or less, the pad will be lighter than the color block on the package and should indicate FAIL. If the solution contains 0.45% OPA or more, the pad color will be equal to or darker than the color block and should indicate PASS. At intermediate concentrations of OPA, the test strip may indicate either PASS or FAIL.
A 12x75 glass test tube is provided with the strips for use in testing samples of CidexTM OPA solutions. About 1 ml of CidexTM OPA solution is placed in the glass test tube. After immersing the strip in the CidexTM OPA solution for exactly 30 seconds, the test strip is removed by touching the side edge of the pad against the inside of the tube and is drawn upward for 2-3 seconds against the entire length of the test tube. The handle end of the strip is laid on a paper towel so that the indicator pad hangs over the edge to prevent further absorption. After 2.5 minutes following removal of the strip from the solution, the color of the indicator pad is compared to the color block on the container.
Comparison Products
The firm noted that the CidexTM OPA Solution Test Strip is similar in design, composition and function to the CidexTM Solution Test Strips (K915170; a.k.a., PyMah Sterilog Indicator Strips). The firm has provided a table comparing the indicator strips.
Labeling
The firm has provided the proposed labeling for the CidexTM OPA strips. The label includes the intended use, warnings and precautions, directions for use, information on how to interpret the results, a reference color chart, the chemical principle, performance characteristics, quality control procedures, and a statement indicating that the strips should not be used as a means of validating a sterilization process. The storage instructions indicate that the strips should be stored in a dry place at 16-32oC and used within 90 days after opening the bottle and not used after the expiration date.
In the package insert, the firm provides the following information to the user:

K992341 Page 3
Leaving the strip in the CidexTM OPA solution for longer than 30 seconds or swirling the strip
vigorously could cause excess color development and lead to a false PASS result when the
OPA concentration is truly below the MEC.
A false pass may result if the indicator pad is not drawn up the tube slowly (2-3 seconds);
the use of the provided test tube is important to the performance of the strip.
Reading the strip after a total of 3 minutes may also result in a false PASS result.
Fresh solution should be used for each strip.
These aspects of the strips are addressed with performance testing.

Re: 510(k) Submission for Cidex@ OPA Solution Test Strips
To Whom it May Concern:
Germicides that are labeled for reuse can be used safely and effectively only if the user has a chemical indicator available to measure the level of active ingredients in the germicide solutions. The Cidex@ OPA Solution Test Strips (the subject of this submission) are semi-quantitative chemical indicators used to determine whether the concentration of active ingredient in Cidex@ OPA Solution is above or below the minimum effective concentration (MEC).
The Premarket Notification [510(k)] for the germicide, Cidex@ OPA Solution, has been submitted separately (K991487) by Advanced Sterilization Products, a Johnson & Johnson

DEVICE NAME
Trade Name: CIDEX® OPA Solution Test Strips
Common Name: Test Strips for ortho-Phthalaldehyde (OPA) in CIDEX© OPA Solution
Classification Name: Chemical Sterilization Process Indicator
PREDICATE DEVICE
Cidex© Solution Test Strips (K915170)
DESCRIPTION OF THE CIDEX® OPA SOLUTION TEST STRIP
The CIDEX® OPA Solution Test Strips consist of a 0.2 x 0.2-inch reagent-containing pad attached to one end of a 0.2 x 3.25-inch polystyrene handle. The indicator pad contains a color-forming reagent. It also contains an inhibiting compound that prevents visible reaction when the OPA concentration is at or below the MEC. When the OPA level is in sufficient excess of the MEC, the surplus reacts with the color-forming reagent.
The sample is placed in a 12 x 75-mm glass test tube. The indicator pad is immersed in the sample for 30 seconds, removed and allowed to react for an additional two and one-half

minutes at which time it is compared to a color standard. If the color of the entire pad is
__ equal to or darker than the color standard, the concentration of ortho-phthalaldehyde (OPA)
in CIDEX@ OPA Solution is above the minimum effective concentration (MEC). If any part
of the pad is lighter than the color standard, the CIDEX@ OPA Solution should not be used.
INTENDED USE
CIDEX@ OPA Solution Test Strips are semi-quantitative chemical indicators used to
determine whether the concentration of OPA in CIDEX@ OPA Solution is above or below
the MEC. CIDEX® OPA Solution Test Strips cannot be used to validate the disinfection
process.
TECHNOLOGICAL COMPARISON TO THE PREDICATE DEVICE
CIDEX@ OPA Solution Test Strips are used for determining OPA in CIDEX@ OPA
Solution whereas the CIDEX@ Solution Test Strips are used for determining glutaraldehyde
levels in CIDEX@ Activated Dialdehyde Solution. Both tests have dry, reagent-containing paper indicator pads attached to plastic handles. Both pads contain an inhibitor that prevents
reaction with an indicator at ineffective active ingredient concentrations.
The reaction pad of the CIDEX@ OPA Solution Test Strips is observed three minutes after
the strip is immersed in the solution while that of CIDEX© Solution Test Strips is read
between five and eight minutes after immersion. For interpretation of the result, the indicator
pad of the CIDEX@ OPA Solution Test Strip is compared with a standard color block. The
CIDEX@ Solution Test Strips use a visual standard for interpretation of the result.
STATEMENT OF SUBSTANTIAL EQUIVALENCE
Eight individuals used CIDEX@ OPA Solution Test Strips from three trial production lots in
blind studies to test CIDEX® OPA Solution standards. Three of the readers were inexperienced in laboratory techniques. A total of 324 results were obtained with each standard.
At the MEC (0.30% OPA), 324 results were FAIL giving a specificity (lack of false PASS
results) of 1.00. At 0.40% and 0.45% OPA, 322 and 324 results, respectively, were PASS.
These results show that the CIDEX@ OPA Solution Test Strips effectively indicate when the
OPA concentration in CIDEX@ OPA Solution is at the MEC of 0.3%.

CIDEX® OPA Solution Test Strips Enclosure A-Package Insert
A. INTENDED USE CIDEX' OPA Solution Test Strips are semi-quantitative chemical indicators used to indicate whether the concentration of ortho-phthalaldehyde (OPA), the active ingredient in CIDEX® OPA
Solution, is above the minimum effective concentration (MEC) of 0.3% OPA. It is recommended that CIDEX® OPA Solutions be tested before each usage with CIDEX' OPA Solution Test Strips.
WARNING - CIDEX® OPA Solution Test Strips cannot be used to validate the disinfection process. Do not use CIDEX' OPA Solutions beyond the 14-day maximum use life even if the test strip shows the solution is above the MEC.
B. PRINCIPLE OF THE TEST PROCEDURE
The filter paper square (indicator pad) mounted on the end of plastic strip comprises the reactive portion of the CIDEX' OPA Solution Test Strip. The indicator pad contains an inhibitor and a
color-forming reagent. If the concentration of OPA is at or below the MEC, the inhibitor will prevent any color formation. If the concentration of OPA is present in excess of the inhibitor, it reacts with the color-forming reagent to form colored pigments.
C. STORAGE
Proper storage and handling of test strips is important to maintain proper product performance. Store CIDER' OPA Solution Test Strips in the original bottle with the cap tightly closed. Store in a dry place at controlled room temperature; 16°-32° C (6l°-90° F).
The expiration date for unopened bottles of CIDEX® OPA Solution Test Strips is printed on each bottle label.
Open Bottle Shelf Life When opening a bottle of CIDEX®OPA Solution Test Strips for the first time, record the date opened in the space provided on the bottle label ("Date Opened "). Strips may be used up to 90 days after first opening the bottle if the cap is promptly replaced and tightened after removal of each strip. Do not use test strips (from an opened or unopened bottle) after the expiration date. Each kit contains two bottles of strips and two test tubes. For optimal results, use a new test tube with each new bottle of strips.
D. SAMPLE COLLECTION and PREPARATION
Pipette or dispense approximately 1 mL of room temperature CIDEX® OPA Solution into the 12x75-mm glass test tube provided. (The tube should be approximately 1/5 full, allowing the indicator pad on the test strip to be fully immersed in the sample.) Caution: Use only the test tube provided.

E. DIRECTIONS FOR USE
NOTE: Prior to starting routine use of the CIDEX® OPA Solution Test Strips, practicing the
testing technique with control solutions (the preparation of which is described in Section H., "QUALITY CONTROL")will familiarize the user with proper testing technique and interpretation of results.
Test Procedure:
1. Dispense approximately 1-ml, of CIDEX® OPA Solution into the 12x75-mm glass test tube. The test tube should be approximately 1/5 full.
2. Dip the test strip into the sample for exactly 30 seconds making sure that the indicator pad is fully immersed.
3. At 30 seconds, remove the test strip by touching the side edge of the indicator pad against the inside of the test tube and draw upward (for approximately 2-3 seconds) against the entire length of the test tube, gradually removing excess sample. (See Figure 1.)
Figure 1
4. Lay the handle end of the test strip on a paper towel so that the indicator pad hangs over the edge of the towel to prevent absorption of the sample solution.
5. Compare the color of the indicator pad to the color block on the bottle label at exactly 3 minutes after the test was started (21/2 minutes after removing the strip from the test tube.)
6. Use the logbook in CIDEX® Solutions Information Station (Reorder No. 20251) to record results.
7. Discard the test strip and CIDEX® OPA Solution test sample in accordance with federal, state, local and institution guidelines. Rinse the test tube with Enzol® or equivalent
detergent, then rinse the test tube thoroughly with distilled water. Dry completely prior to next use.
*Note: For optimal results, use a new test tube with each new bottle of strips.

F. TEST RESULTS INTERPRETATION
The color developed on the CIDEX® OPA Solution Test Strip Indicator Pad is used to determine whether the concentration of OPA in the sample is above or below the MEC of 0.3%.
" For a "PASS", the entire indicator pad should be equal to or darker than the gray color block on the bottle label.
" If the entire indicator pad is lighter than the color block on the label or distinct areas of lighter
color are observed, the result is a "FAIL". The CIDEX® OPA Solution is at or below the MEC and must be discarded.
At concentrations slightly above the MEC the indicator pad may have a mottled appearance.
However, if any portion of the indicator pad is lighter than the color block, the results should be
considered a "FAIL".
NOTE: False "FAILS" may occur as the MEC is approached. This is due in part to a safety
margin provided by the test strip ensuring that solutions at or below the MEC will
"FAIL"virtually 100% of the time.

H. QUALITY CONTROL PROCEDURES
Testing Frequency:
It is recommended that the testing of positive and negative controls be performed periodically. Each facility should determine the frequency of control testing for its own QC program. Regular
testing of the control solutions will increase user proficiency, minimize procedural errors and protect against the inadvertent use of outdated product or product that has deteriorated due to improper storage or handling.
Preparation and Testing of Control Solutions:
Verify that the CIDEX® OPA Solution has an acceptable expiration date. Label two tubes, one for the positive control and one for the negative control. To prepare a positive control use fresh, full strength solution. To prepare a negative control, dilute one part of full strength solution with one part of distilled water. Following the "Directions for Use" (Section F), dip one test strip in the positive control and one in the negative control.
Results for Control Solutions:
Refer to the color block on the test strip bottle for interpretation of results.

At 3 minutes, the test strip dipped in the full strength positive control solution should exhibit a
completely gray/black color on the indicator pad equal to or darker than the color block on the
bottle label. The test strip dipped in the negative control should show a color lighter than the color block on
the bottle label when read at 3 minutes. If the results obtained from using the positive and negative controls indicate the test strip is not
performing as expected, do not use the remaining strips, but retain them for possible return to
Product Quality Services. For technical product information and support, contact Advanced Sterilization Products at 1-888-783-7723.
I. PERFORMANCE CHARACTERISTICS
The performance characteristics of CIDEX° OPA Solution Test Strips are based on testing samples of CIDEX' OPA Solution of known ortho-phthalaldehyde concentrations that are at and above the MEC. The analytical method used to determine the ortho-phthalaldehyde concentration in these samples is High Pressure Liquid Chromatography with UV detection. The CIDEX' OPA Solution Test Strips have been designed to indicate "FAIL"
virtually 100% of the time at and below the MEC of 0.3% ortho-phthalaldehyde (OPA).
J. WARNINGS and PRECAUTIONS
" Replace and tighten cap immediately after removing strip. " Do not touch indicator pad. " Protect strips from chemicals or contaminated surfaces. " Use strips within 90 days after opening bottle. " Protect strips from exposure to extremes of heat, light and moisture. " Do not ingest the strip or allow the indicator pad to come in contact with the eye. " Do not remove desiccant pack from bottle. Keep desiccant out of reach of children. " For optimal results, use a new test tube when opening a new bottle of strips. " Discard used or expired CIDEX' OPA Solution Test Strips in an appropriate waste receptacle
in accordance with federal, state and local laws and your facility's regulations. " CIDEX' OPA Solution Test Strips cannot be used as a means of validating the disinfection
process.
CIDEX® OPA Solution Test Strips are designed specifically to detect ortho-phthalaldehyde.
They cannot be used to measure other disinfectants and should only be used to test CIDEX® OPA Solution.

UNDERSTANDING THE TESTING TECHNIQUE:
It is important that the "DIRECTIONS FOR USE" be followed closely to achieve optimal test results. Outlined below is an explanation of the significance of the technique for each step in the
Test Procedure. This information may be useful for training and troubleshooting.
" Leaving the test strip in the sample of CIDEX® OPA Solution for longer than 30 seconds or
swirling the strip vigorously could cause excess color development. This could lead to a false "PASS"
result, i.e., the concentration of OPA in the solution is truly below the MEC, but due to improper technique the test strip gives a "PASS" result.
" Removing the test strip too soon from the solution or blotting the indicator pad with an
absorbent material such as a paper towel could cause insufficient color development. This could cause a false "FAIL" result when the solution would normally pass.
" It is important to use the 12x75-mm glass test tube provided. The procedure and timing were optimized using this specific test tube
" Failure to draw the side edge of the indicator pad slowly (for 2-3 seconds) up the inside of the test tube could lead to a false "PASS" due to retention of excess sample.
" Thoroughly clean, rinse and dry the test tube between each use. For optimal results, use a new test tube with each new bottle of strips.
" Although excess sample solution must be allowed to drain from the indicator pad, it is important not to remove too much solution. Therefore it is recommended that once the test
strip is removed from the test tube, the indicator pad should not come in contact with an absorbent surface. The test tube wall removes the proper amount of sample as opposed to paper towels, which have a tendency to absorb an excessive amount of solution from the indicator pad.
Note: The use of this test tube/sample removal technique provides significantly improved and consistent results when compared to alternate sample removal methods used with other tests (i.e., blotting or shaking excess liquid from the indicator pad.
" It is important to interpret the results of the test strip exactly 3 minutes after starting the test
(dip for 30 seconds, then allow reaction to develop for an additional 21/2 minutes).
" If the test is read in less than 3 minutes, the color change may be incomplete and a solution could give a false "FAIL" result. If the test is read after 3 minutes, excess color may develop and the solution could yield a false "PASS" result.
" The test strip may take on a mottled appearance as it approaches the WC. Appearance of istinc areas of color lighter than the color block is considered a'TAIL" result.
" Only one test strip per one mL of sample may be dipped. If the test is repeated, 1 mL of fresh sample is required.

CIDEX* Family of Solutions Test Stri
The CIDER' Family of Solutions Test
Strips are semi-quantitative chemical indicators for use in determining whether the concentration of glularaldehyde, the active ingredient in CIDER Disinfecting and Sterilizing Solutions, is above or below the minimum effective concentration
(MEC) established for each of the CIDER Solutions. CIDER Solutions Test Strips cannot be used to validate the sterilization or disinfection process.
CIDER Solutions Test Strips are developed exclusively for monitoring the effectiveness of CIDER Solutions. Each CIDER Solution formulation has its own test strip (i.e., CIDER Solution Test Strip, CIDER FORMULA
7'
Solution Test Strip, CIDER PLUS'
Solution Test Strip), specifically designed for its MEC and accurate results. It is recommended that CIDER Solutions be tested before each usage with the appropriate CIDER Solutions Test Strip in order to guard against dilution, which may lower the glutaraldehyde level of the solution below its MEC.
WARNING: Do not use CIDER Solutions beyond the 14 or 28 day maximum use life of the solution.
Glutaraldehyde reacts with sodium sulfite in the test strip to form a sulfite addition product and an equivalent amount of base. If sufficient glutaraldehyde is present, it further reacts with sodium glycinate in the test strip to form yellow colored addition products in the following manner:

the test strip into the container of the CIDER Solution being tested for one second and remove. Do not leave the strip in the test solution for Innner than nnp "conri or -stir the test strip in the solution. Incorrect
dipping technique, such as dipping much longer than the specified 1 second and/or swirling the test strip vigorously in the solution, will wash off the reagents in the test strip pad; this can cause a lack of yellow color formation (FAIL) when testing a solution that will normally lest as PASS.
2. Remove excess solution from the
indicating pad by touching the long edge of the indicating pad to a paper towel. Do not shake the strip after removal. When removing excess solution, incorrect technique, such as violently shaking the test
strip and/or blotting the test strip with the pad face down against a paper towel, can remove the reagents and solution, which ran again cause FAIL results for solutions that will normally test as PASS.
Read the results of the color reaction present on the indicating pad between 5 and 8 minutes after the test strip is removed from the solution. It read in less than 5 minutes, the color change may be incomplete and may be interpreted incorrectly. (NOTE: Positive results
may be obtained in as early as 3 minutes when CIDER Solutions are tested immediately alter activation, or one or two days after activation when the solution has been reused less than three cycles per day). Do not read the pad after 8 minutes, as the color will gradually fade making interpretation difficult. The pad will be completely yellow to indicate an effective solution. Any shade of . yellow is acceptable; the intensity will vary due to concentration variation. If any white remains on the indicating pad, the CIDER Solution is ineffective (below the MEC) and should be discarded. Refer to the visual standard on the test strip bottle for interpretation of test results. Use
log book in CIDER Solution Information Station (Reorder No.
20251) to record results. See Section I, Test Strip Interpretation, for additional important information
M Materials Required
The following materials are not provided with the CIDER Solutions Test Strips but will be needed for the test:
" watch or timer " paper towel " If the solution cannot be tested
directly in the tray, bucket or container in which it is being held, a clean polyethylene or polypropylene container will be required to hold the ulutx Solution sample.
Preparation of Control Solutions To prepare positive and negative control solutions for testing, first
verily that the labeled expiration date for the unadivated solution is appropriate. Activate the CIDER Solution according to
labeling instructions. This freshly activated, full strength solution may be used as a positive control. To prepare a negative control, dilute one pan of full strength solution with one part of water. Label each control solution appropriately.

2. Testing Procedure Following the Directions for Use, dip three test strips in each of the above freshly prepared solutions. The three strips dipped in the full strength positive control solution should exhibit a completely yellow color on the indicating pad within 5 to 8 minutes. The three strips dipped in the diluted negative control should either remain
completely white or exhibit an incomplete color change to yellow when read at 5 to 8 minutes. Refer to the visual standard on the test strip bottle for interpretation of results.
3. Testing Frequency It is recommended that the testing of positive and negative controls be performed on a newly opened test strip bottle from each case of CIDER Solutions Test Strips that is received. After this initial testing, it is recommended that testing of
freshly prepared positive and negative controls be performed on a regular basis as established by your own quality control procedures and program. This testing program will serve to minimize errors between different users, use of outdated materials or product that has been improperly stored or handled.
4. Unsatisfactory OC Test Performance If the results obtained from using the positive and negative controls indicate the test strip is not
functioning properly, discard the
remaining strips. Do Not Use. For technical product information, contact Johnson & Johnson Medical. Inc., Product Quality Services, 1-800-423-5850 or contact your local JJMI sales representative.
5. Storage
Keep the cap on bottles of CIDER Solutions Test Strips tightly closed. Store at controlled room temperature, 15`-30"C (59°-86°F) and in a dry place. Do not remove desiccant from bottle. Do not store in a refrigerator or freezer.
CAUTION: Do not use remaining CIDER Solutions Test Strips 90 days after opening the bottle.
Following the one second dip in the CIDER Solution being tested and removal of excess solution from the pad by touching the long edge to a paper towel, the CIDER Solutions Test
Strip should be compared to the color chart provided on the test strip bottle after 5 to 8 minutes. The entire
indicating pad must be completely yellow to pass the test indicating an effective solution. If any white remains on the indicating pad this is a failure, verifying the solution is ineffective and should be discarded. As the minimum effective concentration (MEC) of CIDER Solutions is approached during
the maximum use life after activation, the lest strip will give some PASSES and some FAILS. This is due to the inherent variability of the test strip and is part of the large safety margin provided by the test strip for 100% TB kill. FAIL indications based on reading the test strips, especially when read after less than 5 minutes, are not unusual after less than the maximum number of days for reuse for the CIDER Solution, especially ii the usage by the customer is greater than 3 cycles per day or dilution by the customer is heavy. As the CIDER Solution is being reused, read the strip at between 5 and 8 minutes, but not more than 8 minutes, to get consistent results after the solution has undergone more than a few days of reuse.
Although CIDER Solutions Test Strips
may give a color reaction with glutaraldehyde-based disinfectants from other manufacturers, their use is limited to the specific CIDER Solution indicated. Disinfectants from other manufacturers may claim different MECs which will lead to inaccurate test results using CIDER Solutions Test Strips.
It is also important to point out that CIDER Solutions Test Strips will not detect failure to add the activator to the CIDER Solutions.
The performance characteristics of CIDER Solutions Test Strips are based on testing strips on samples of CIDER Solutions with known concentrations of glutaraldehyde at the minimum effective concentration
(MEC) and above the MEC for each individual CIDER Solution (CIDER Activated Dialdehyde Solution, CIDER FORMULA 7 Long-Life Activated Dialdehyde Solution and CIDER PLUS 28 Day Solution). The analytical method used to determine the glutaraldehyde concentrations in these samples is based on the reaction of glutaraldehyde with hydroxylamine hydrochloride followed by the titration of released hydrochloric acid with a standardized solution of sodium hydroxide. I
The performance of CIDER Solutions Test Strips has been designed to indicate FAIL 100% of the time at the MEC of glularaldehyde for each CIDER Product as shown below:
MEC TEST STRIPBOLUTION (°Y. GLUTARALOHYDE) CIDER 1.5°e DIDEX FORMULA 7 1.8% CIDER PLUS 2,1°0
Since the accuracy and sensitivity limit of CIDER Solutions Test Strips is
approximately " 0.25°<, at concentrations of 0.25% above the MEC shown above for each CIDEX
Solution, the corresponding test strips will indicate FAIL about 50°0 of the time and PASS about 50°a of the time.
-9-
This provides the user with a high margin of safety. An independent publication has confirmed that concentrations of greater than 190 glutaraldehyde are required for total kill of Mycobacterium tuberculosis 2 The
MEC for each CIDER Solution is based on its ability to give 100% TB kill.
1. Discard used or expired test strips in a trash receptacle in accordance with federal, state and local laws.
2. Keep desiccant (silica gel) out of reach of children.
3. Do not ingest the strip and7or expose to the eye.
4. Chemical indicators such as CIDER Solutions Test Strips cannot be relied upon as a means of
validating the sterilization or disinfection process. Chemical indicators can only establish that a specific factor exists within the specified limits of performance of the indicator.
