proficiency testing samples

Proficiency testing samples are standardized materials used to evaluate and verify the accuracy and consistency of a laboratory’s testing processes. Laboratories analyze these samples just as they would real patient or sample specimens. The results are then compared to known reference values to determine if the laboratory’s methods and procedures are reliable. This process helps identify errors and ensures quality control, maintaining trustworthy and accurate testing outcomes for patients and clients. In essence, proficiency testing samples serve as a benchmark to assess and improve laboratory performance.
