This document describes general requirements, procedures and performance criteria for evaluating the content of genetically modified (GM) seeds\/grains in a lot by a group testing strategy that includes qualitative analysis of sub-sampled groups followed by statistical evaluation of the results.<\/p>\n
This document is applicable to group testing strategy estimating the GM content on a percentage seed\/grain basis for purity estimation, testing towards a given reject\/accept criterion and for cases where seed\/grain lots are carrying stacked events.<\/p>\n
This document is not applicable to processed products.<\/p>\n
