DNA Proficiency Test

The aim of the proficiency test is to check the ability of individual laboratories to obtain DNA profiles using the marker sets in the Rules. These DNA profiles will be compared against a Reference Matrix using two parameters, the number of varieties wrongly rated and the number of markers with wrong results. The proficiency test is aimed to test laboratory performance and is mandatory for ISTA Accredited laboratories performing DNA tests on wheat and having this test in the accreditation scope
