ADVANTAGES

When evaluating your performances with Progetto Trieste proficinecy testing schemes you will have several advantages, among them:

  • International PTs: in 2022 participants were from 87 countries from all the continents.
  • Progetto Trieste is EN ISO/IEC 17043:2010 accredited and Test Veritas has 25 years of experience as a proficiency testing provider.
  • Separate evaluation for screening and confirmatory results, the assigned value derives only form 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).

  • Often the participation provides 2 different Test Materials, (they can be both contaminated or one of them could be blank). In the PT, as in the routine, the laboratory technician does not know if he/she is testing a contaminated material or a blank material. Providing 2 different Test Materials, the laboratory could be assessed also for False Positive results or for how the method operates at different leves of concentrations.
  • Participants that use a confirmatory method, receive the information about a possible False Positive in the Final Report.
