proficiency tests

Proficiency tests are assessments that evaluate the quality and accuracy of laboratory or testing processes. They involve an organization sending known samples to different labs to see if they can produce correct results. The goal is to ensure that labs maintain reliable, accurate, and consistent testing standards. These tests help identify areas for improvement and confirm that testing methods meet industry or regulatory standards. Essentially, proficiency tests act as a quality check, providing confidence that the results generated by a lab are trustworthy and accurate.
