How Proficiency Testing Can Foster Quality Assurance
June 8, 2017
Any laboratory can report results, but how can you be sure of the quality of those results? It’s a question customers should ask of any laboratory providing results: “How do I know my results are correct?” Laboratory inspections, which include checking a lab’s procedures and equipment, are one piece of the puzzle. The other less commonly looked at piece is a lab’s proficiency testing results.
What is proficiency testing?
Proficiency tests, also referred to as “round robin tests” or “ring trials”, are intended to check the actual analytical performance of a laboratory. Identical samples are sent out to laboratories who have actively decided to participate in a PT round or scheme. All of the participants individually analyze the samples and results are collected in a designated time frame. At this point, a statistical analysis will be performed by the PT round provider to evaluate the accuracy of the laboratories. According to DIN EN ISO/IEC 17025, accredited testing laboratories must participate in proficiency testing regularly in order to ensure the quality of their analyses.
