  • With us the convenience doubles! For all the PTs that are part of Progetto Trieste it is possible to submit 2 sets of results: with just one subscription you can receive in the Final Report the evaluation of 2 laboratory technicians, or 2 different techniques.
  • Separate evaluation data for screening and confirmatory methods, with the assigned value deriving only from quantitative confirmatory results. 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.
  • Even if you are using a screening method, the PT simulates what you would do in the routine (comparing your results with confirmatory ones). The semi-quantitative (< or >) screening results receive evaluations provided with dedicated criteria. The quantitative screening and confirmatory results are evaluated through z-score.
  • Whenever possible, we supply naturally contaminated test materials that allow the laboratory to assess the extractive capacity of the method used.
  • More reliable assigned value due to more stability of Test Materials. Most of them are provided as lyophilized (to be tested after reconstitution). In this way, regardless of the provenience of the laboratory, every participant can be sure to receive the Test Material in the same conditions. Once reconstituted it is the same as in your routine!
  • Test Veritas has more than 25 years of experience as PT provider.
