The present guidelines for conducting a collaborative validation study of qualitative real-time PCR methods were developed by the international working group "Development of methods for the identification of food produced by genetic engineering" established pursuant to § 64 of the German Food and Feed Code. It aims to ensure that respective methods can meet the performance criteria defined at the European (ENGL, CEN) and international (ISO, Codex) level. The main criterion for validation a qualitative real-time PCR method by means of a collaborative study is determining the false-positive rate and false-negative rate. However, the robustness of the method can also be derived from the study as different laboratories use different real-time PCR equipment. On the basis of a mathematical-statistical model for the validation of the probability of detection (POD) of qualitative PCR methods, performance characteristics regarding laboratory standard deviation, mean amplification probability and LOD95% (across laboratories) can be computed.

The procedure described in this document is a recommendation that is underpinned by practical experience but alternative approaches for which it can be shown that performance criteria are achieved can be applied.
Please consider that a qualitative real-time PCR method should first undergo single-laboratory validation before being tested in a collaborative study (refer to BCH-VLR-SCBD-293575-1 ).
