a, b: Marked samples derive from corresponding stock materials diluted in consecutive steps.

Non-marked samples derive from independent preparations. # FSME = Frühsommer-Meningoenzephalitis

* For highly concentrated samples some commercial tests for the detection of anti-HAV-IgG or anti-HAV-total reveal values > 60 mIU/ml, which are outside the linear measurement range of the respective test system. Therefore, a final target value derived from a consensus value from all results stated in mIU/ml could not be assigned to highly concentrated samples. In this case a lower limit value in mIU/ml is indicated in order to assess a reported result of a laboratory as a "correct" result.

Notices

Evaluation of results for quantitative genome detection of CMV

1 Notice for German and foreign participants of EQA scheme 365: For evaluation, "IU/ml" have primarily been considered as measurement units of the quantitative results for the analyte CMV. This is in accordance to the "Guideline of the German Medical Association (Bundesärztekammer / RiliBÄK)", Specified RiliBÄK Section B 3, Table B. 3-2a,

When applying CE-marked tests, which not (yet) allow reporting of results in IU/ml, it should be continued to report the results as stated by the manufacturer.

Evaluation of results for quantitative genome detection of HBV and HCV

2 Notice for German participants of EQA schemes 361 and 362: For evaluation, "IU/ml" have been considered as measurement units of the quantitative results for the analytes HBV and HCV. This is in accordance to the "Guideline of the German Medical Association (Bundesärztekammer / RiliBÄK)", Specified RiliBÄK Section B 3, Table B. 3-2a. Statements in "copies/ml" will not be accepted anymore.

3 Notice for foreign participants of EQA schemes 361 and 362: Please note that quantitative results in "copies/ml" for the genome detection of HBV and HCV, respectively, have not been evaluated due to the low number of analyses or missing analyses.

Evaluation of results for quantitative genome detection of HIV-1 (RNA)

4 Notice for German participants of EQA scheme 360: For evaluation, "copies/ml" have been considered as measurement unit of the quantitative results for the analyte HIV-1 (RNA). This is in accordance to the "Guideline of the German Medical Association (Bundesärztekammer / RiliBÄK)", Specified RiliBÄK Section B 3, Table B. 3-2a. Statements in "IU/ml" will not be accepted anymore.

5 Notice for foreign participants of EQA scheme 360: Please note that quantitative results in "IU/ml" for the genome detection of HIV-1 (RNA) have not been evaluated due to the low number of analyses or missing analyses.

§ The samples 387021 and 387024 are identical.

* For sample 359040 (1 : 375 diluted), the reporting of "indeterminate" in test category 10 (Qualitative detection of RSV antigen) was

accepted as additional correct result for rapid tests for antigen detection of RSV. Considering also the result "indeterminate" ensured

that this positive sample would not have been misinterpreted as negative.
