Proficiency test
Proficiency testing, or interlaboratory comparison, is a process used by groups of laboratories to monitor measurements, results, and to continually evaluate performance. Each laboratory participating in a proficiency test will analyse the same set of samples and report their results to a third party accreditor. The accreditor evaluates the measurements from each participant and produces a report. The results of a proficiency test allow laboratories to measure their performance against other participants, gaining a better understanding of their processes and procedures, and meet legislative requirements.
