Proficiency tests
The aim of proficiency test (PT) is to assess the ability of individual laboratories to detect the presence or absence of GM seeds and to quantify and identify their presence in samples of conventional seeds. Participants may choose their own methods. Since GMO testing has been included in the ISTA Accreditation Programme, participation in the ISTA PTs on GMO testing is compulsory for those laboratories currently in the process of accreditation in GM seed testing. The first PT was launched in 2002.
Proficiency test data rating
Rating systems for qualitative (presence/absence) and quantitative results are developed and tested by the ISTA Statistics Committee. Detailed information was published in Seed Testing International Nos. 128 (qualitative rating) and 130 (quantitative rating).
