  • International PTs with many participants: in 2020, for PTs for Veterinary Drug Residues in honey there were 52 participants from 27 Countries from all the continents.

  • Progetto Trieste is EN ISO/IEC 17043:2010 accredited proficiency testing scheme is and Test Veritas has more than 20 years of experience as proficiency testing provider.

  • Separate evaluation data for screening and confirmatory methods, with the assigned value deriving only from quantitative confirmatory results.

  • Even if you are evaluating a screening method, the PT simulates what you would do in your routine (comparing your results with the confirmatory ones).

  • This feature of our PTs respects the requirement of UNI CEI EN ISO/IEC 17043:2010 to use fit-for-purpose methods of evaluation, makes the assigned value more reliable and the assessment more valid.

  • Almost every participation provides 2 different Test Materials for each participation.  During the PT, as in the routine, the laboratory shouldn’t know if he is testing a contaminated Test Material or a blank Test Material. Providing 2 different Test Materials, one could be blank (or not), so the laboratory is fully assessed also for False Positive results. Moreover, receiving 2 Test Materials allows to evaluate how the method performs at different levels of concentration.
