This review deals with recent information on important international european programs in molecular biology. We briefly characterize main European schemas for DNA analyses. Also we introduce list of analytes and methods used for assessment. Narrow connection between analytical and postanalytical processes is very important and typical characteristic for these programs. Published results reached in these programs clearly show their necessity as tool for education of laboratory personal. Proficiency of laboratories performed DNA analyses is not enough sufficient.
