Homogenität und Stabilität / Homogeneity and stability

Homogenität Homogeneity

Die Homogenitätsuntersuchungen des Pro-

benmaterials und die anschließende statisti-

sche Bewertung gemäß Abschnitt B.2.3 b)

der ISO 13528 [1] erfolgte durch die

QSE GmbH. Alle Ringversuchsproben kön-

nen in Bezug auf alle Untersuchungsparame-

ter als ausreichend homogen angesehen

werden.

The homogeneity analysis of the test material

as well as the subsequent statistical evaluation

according to Section B.2.3 b) of ISO 13528 [1]

were carried out by QSE GmbH. All proficiency

test samples are sufficiently homogeneous

with respect to all test parameters.

Stabilität Stability

Aufgrund langjähriger Erfahrungen der

QSE GmbH kann je nach Probenmaterial

eine Stabilität zwischen 6 Monaten und

3 Jahren gewährleistet werden. Die Ringver-

suchsproben wurden von den Laboratorien

jeweils vor Ablauf des Mindesthaltbarkeitsda-

tums analysiert und können somit als ausrei-

chend stabil angesehen werden.

Based on QSE GmbHs longstanding experi-

ence, stability between 6 months and 3 years

can be ensured, depending on the sample

material. The proficieny test samples were

analyzed by the laboratories before the expira-

tion date and can thus be considered to be

sufficiently stable.

Sollwert �� Assigned value ��

Der Sollwert (assigned value ��) wird durch

die robuste Mittelwertschätzung nach Ham-

pel (vgl. Abschnitt C.5.3 in ISO 13528 [1])

aus den Ergebnissen aller Laboratorien er-

mittelt. Dabei handelt es sich um ein gewich-

tetes arithmetisches Mittel, bei dem stark

abweichende Werte automatisch geringer

gewichtet werden. Eindeutige „Ausreißer“

haben das Gewicht Null, gehen also nicht in

die Mittelwertberechnung ein. Eine Ausrei-

ßerprüfung ist nicht erforderlich.

The assigned value �� is determined as the

robust mean value using the Hampel estimator

(see Section C.5.3 in ISO 13538 [1]) on the

basis of the results of all participating laborato-

ries. It is a weighted arithmetic mean, with

lower weights for the outlying values. Obvious

“outliers” have the weight zero and have no

influence on the mean value. An outlier test is

not required.

Sollwert der Standardabweichung �� Standard deviation for proficiency assess-ment ��

Als Sollwert der Standardabweichung ��

wird die robuste Vergleichstandard-

abweichung gemäß Q-Methode (vgl. Ab-

schnitt C.5.2 in ISO 13528 [1]) heran-

gezogen.

The standard deviation for proficiency

assessment �� is determined as the robust

reproducibility standard deviation according to

the Q method (see section C.5.2 in

ISO 13538 [1])

Unsicherheit des Sollwertes Uncertainty of the assigned value

Die Standardunsicherheit des Sollwertes

�� wird gemäß Abschnitt 7.7.3 in

ISO 13528 [1] wie folgt berechnet:

(��) = 1,25 ∙�∗

��

wobei � die Anzahl der Laboratorien sowie �∗

die robuste Standardabweichung der Labor-

mittelwerte gemäß Q-Methode bezeichnen.

Die erweiterte Unsicherheit � des Sollwertes

�� wird durch Multiplikation der Standard-

unsicherheit mit dem Erweiterungsfaktor

� = 2 berechnet, d. h.

�(��) = � ∙ (��) = 2 ∙ (��)

The standard uncertainty of the assigned

value �� is calculated as follows according to

Section 7.7.3 in ISO 13528 [1]:

(��) = 1.25 ∙�∗

��

where � is the number of laboratories and �∗

the robust standard deviation of the

laboratories mean values using the Q method.

The expanded uncertainty � of the assigned

value �� is calculated by multiplying the

standard uncertainty with the coverage factor

� = 2, i.e.

�(��) = � ∙ (��) = 2 ∙ (��)

Gemäß Abschnitt 9.4.1 der ISO 13528 [1] wer-

den die �-Scores für die Bewertung der quanti-

tativen Ergebnisse der Laboratorien im

Rahmen einer Eignungsprüfung entsprechend

der folgenden Gleichung berechnet:

�� =�� − ��

wobei �� das Laborergebnis (Labormittel-

wert im Fall von Mehrfachmessungen), ��

den Sollwert (Assigned value) und �� den

Sollwert der Standardabweichung (standard

deviation for proficiency assessment) be-

zeichnen.

Ausgehend von einem „well-behaved

analytical system“ schlägt der ISO/IEC

International Standard 17043:2010 [2]

folgende Klassifizierung vor:

|�|≤ 2 Laborergebnis zufriedenstellend

2 < |�| < 3 Laborergebnis fragwürdig

|�| ≥ 3 Laborergebnis unbefriedigend.

Für die Bewertung der quantitativen Ergeb-

nisse der Laboratorien kann weiterhin der

�′-Score herangezogen werden, welcher

zusätzlich die Unsicherheit des Sollwertes

(��) berücksichtigt und wie folgt berechnet

wird:

��$ =

�� − ��

�� + (��).

The � scores for the assessement of quantita-

tive laboratoratory results obtained in the

framework of proficiency testing are calculated

according to the following equation given in

Section 9.4.1 of ISO 13528 [1]:

�� =�� − ��

��,

where �� is the laboratorys result (laboratory

mean value in the case of replicate

measurements), �� is the assigned value and

�� is the standard deviation for proficiency

assessment.

Assuming a ”well-behaved analytical system”,

ISO/IEC International Standard 17043:2010 [2]

proposes the following classification:

|�|≤ 2 satisfactory laboratory result

2 < |�| < 3 questionable laboratory result

|�| ≥ 3 unsatisfactory laboratory result.

The assessment of quantitative

laboratoratory results can also be carried out

on the basis of �′ scores, which take the

standard uncertainty of the assigned value

(��) into account and are computed as

follows:

��$ =

�� − ��

�� + (��).

Statistical analysis of qualitative data


Statistische Auswertung qualitativer Daten / Statistical analysis of qualitative data

Die Laboratorien sollten mit dem IDEXX

Milchträchtigkeitstest über den Nachweis von

trächtigkeitsassoziierten Glykoproteinen (PAGs)

beurteilen, ob die Proben 11 bis 16 von einer

trächtigen oder nicht trächtigen Kuh stammen.

Die Laboratorien übermittelten sowohl die Ex-

tinktionswerte (Ergebnis der Probe abzüglich

des Ergebnisses der Negativ-kontrolle) als auch

die vorgenommene Klassifizierung „träch-

tig / nicht trächtig / erneut testen“. Da es sich

bei der Klassifizierung um eine qualitative

Messgröße handelt, ist eine Bewertung der

Leistungsfähigkeit der Laboratorien mittels

�-Scores nicht möglich.

Im Rahmen dieses Ringversuches werden die

folgenden Bewertungskriterien herangezogen:

Laborergebnis zufriedenstellend:

• Die Probe wird richtig als trächtig bzw.

richtig als nicht trächtig eingestuft, und

• die Extinktionen werden gemäß der IDEXX

Herstellerangaben richtig beurteilt.

Laborergebnis fragwürdig:

• Die Probe wird als „erneut testen“ einge-

stuft, obwohl die Extinktionen eindeutig auf

ein trächtiges oder nicht trächtiges Tier

hinweisen, und

• die Extinktionen werden gemäß der IDEXX

Herstellerangaben richtig beurteilt.

Laborergebnis unbefriedigend:

• Die Probe wird falsch als trächtig bzw.

falsch als nicht trächtig eingestuft, oder

• die Extinktionen werden entgegen der

IDEXX Herstellerangaben falsch beurteilt

(z. B. Extinktionen im Bereich ≥ 0,1 und

< 0,25 werden als nicht trächtig anstelle

von „erneut testen“ eingestuft), oder

The laboratories had to determine whether

samples 11 to 16 come from a pregnant or

non-pregnant cow using the IDEXX milk

pregnancy test for detection of pregnancy

associated glycoproteins (PAGs). The la-

boratories were asked to submit both the

extinction values (test result of the sample

minus the test result of the negative control)

as well as the classification "preg-

nant / not pregnant / re-check". Since this

classification is qualitative, it is not possible

to evaluate the performance of the laborato-

ries using � scores.

In this proficiency test, the following assess-

ment criteria were applied:

Satisfactory laboratory result:

• The sample is correctly classified as

pregnant or not pregnant, and

• the assessment of the extinctions values

was carried out in accordance with the

IDEXX instructions.

Questionable laboratory result:

• The sample is classified as “re-check”,

although the extinctions clearly indicate

a pregnant or non-pregnant cow, and

• the assessment of extinction values is

carried out in accordance with the

IDEXX instructions.

Unsatisfactory laboratory result:

• The sample is incorrectly classified as

pregnant or not pregnant, or

• the assessment of extinction values is

not carried out in accordance with the

IDEXX instructions (e.g. extinction val-

Damit die teilnehmenden Laboratorien sich

darüber informieren können, inwieweit die vom

Labor ermittelte Extinktion von der mittleren

Extinktion über alle Laboratorien abweicht,

werden informativ die resultierenden �-Scores

angegeben. Da die Extinktionswerte keine sta-

tistisch signifikanten Unterschiede zwischen

sen, erfolgte die Ermittlung von Sollwert �� und

classified as not pregnant instead of “re-

ckeck”), or

• only the classification without the extinc-

tion values was submitted.

In order to allow the participating laboratories

to check how far their extinction values devi-

ate from the mean extinction values across

all laboratories, the resulting � scores are

given, for information purposes. Since the

extinction values exhibit no statistically signif-

icant differences between lyophilized and

frozen samples, the determination of as-

signed values �� and standard deviation for

proficiency assessment �� was calculated

independently of the condition of the sample.
