Proficiency Testing (PT) allows for the comparison of analytical results across different laboratories based on established criteria. For ISO 17025 accredited laboratories, successful participation in PT is mandatory; however, many laboratories also participate voluntarily as a demonstration of their competence to accreditation bodies and customers.

Plan your proficiency tests years in advance and carefully select the analytes and test materials that align with your analytical methods. The current program from our partner, Testveritas, is available for download here. The program includes tests for veterinary drug residues, histamines and biogenic amines, pesticides and disinfectants, heavy metals, food additives, mycotoxins, and acrylamide.

The tests are categorized based on the analytical methods used by the participating laboratories:

A: Methods such as HPLC or GC
B: Immunochemical or rapid methods

For each round of proficiency testing, a comprehensive report is generated, which includes all results and statistically relevant evaluations, including z-score analysis, and is made available to all participants.
