Competitiveness of SD BIOLINE Influenza Antigen test
Why should you use “SD BIOLINE Influenza Antigen Rapid Test”?
SD kit can cover all influenza virus type.
SD kit can detect AIV infection in Human (A/H5N1).
SD kit can differentiate influenza virus type A and B
SD kit is very useful as POCT (point of care testing), on-site test.
SD BIOLINE Influenza H5 kit
SD BIOLINE Influenza H5 rapid test is a chromatographic immunoassay for the qualitative detection of hemagglutinin H5 antigen of avian influenza (AI)virus directly from nasal swab/aspirate specimens, throat swab specimens,tracheal aspiratespecimens onAI virus human infectioncases.

Test Principle & Major active ingredient
specimen collection & preparation
① Nasal swab
② Nasal aspirate
③ Throat swab
④ Tracheal aspirate (Especially, test results with the tracheal
aspirate specimens would be recommendable, because the
majority of AIV may exist at the tracheal position.)
specimen collection & preparation
If the specimen should be tested later, swab specimens should be placed into 1 ~ 2 ml of transport media or saline by direct extraction.
Transport media : Use of the following transport media has been tested and found to be compatible with SD BIOLINE Influenza Antigen test.
Saline EMEM+1%BSAPBS EMEM+0.5%BSAPBS+0.5%BSA Trypticase soy Broth+0.5%BSAPBS+0.5%Gelatin Trypticase soy Broth+0.5% gelatin
Special Precautions on Specimen collection & preparation
① Use of fresh sample is very important for getting
accurate results.
② The specimen which have ever been thawed after
freezing may results in decreased test sensitivity
from the deterioration or modification of H5 antigen.
So, repeated freezing and thawing of specimen must
not be used for this test.
③ Finally, to get accurate results, specimen should be
tested as soon as possible after collection.
Test procedure & Interpretation; nasal swab, throat swab
① Transfer assay diluent into test tube (approximately 300uL).
② Insert the patient swab sample into the test tube and mix well.
③ Place the Test Strip into the test tube.
④ Read result at 10 ~ 15 minutes.
Test procedure & Interpretation; nasal aspirate, tracheal aspirate
① Pipet 100uL of assay diluent and 100uL of aspirate specimen int
o test tube. And mix well.
② Place the Test Strip into the test tube.
③ Read result at 10 ~ 15 minutes.

Poultry AIV – human infection Surveillance of Epidemiology case study by Korea CDC
<Step 1>
• Surveillance on Central Hospital around region of
outbreak of AIV
– Review & Collection of hospitalized records
– Collection of blood or respiratory specimen from
possible case or not-caused ARDS
– Laboratory diagnosis at CDC, Dept. Of infectious
disease control
<Step 2>
• If, detection of AIV_human infection possible case,
you should work on enlarged surveillance with all
general hospital adjacent to the region of outbreak
of AIV.

**WHO recommendations on the use of rapid testing for influenza diagnosis ;
- Influenza surveillance should be used to guide the optimal use of RAT (rapid antigen test).
- At the beginning of the influenza season or an influenza outbreak, RAT may influence on clinical decisions and contribute to clinical awareness.
• For the screening test, the Sole H5 Avian Influenza Antigen Rapid Kit in the world
• Accurate detection on H5N1 samples isolated from Human infection cases, with High Sensitivity and Specificity
• With same kits, we’ve got lots of AI positive cases through HPAI (H5N1~H5N9) detection in the farm, market, or laboratory by use of feces or cloacal swab as veterinary use.
• Easy assay procedure: No technical expert and No equipment is required
• Labor & Time saving because of fast results
