Proficiency Testing

What is it?

About the process Proficiency testing is a special type of inter-laboratory comparison study. It is a powerful quality assurance tool that enables laboratories to monitor their performance and compare their results against similar laboratories. CALA’s Proficiency Testing Program is accredited to ILAC:G13 (and ISO Guide 43) and consists, in general, of four samples per study, two studies per year . The analyte concentrations in these samples are unknown to the participating laboratory, which analyses the samples and reports the results for evaluation. Successful participation results in the laboratory obtaining proficient status for the analytes analysed and is used as one of the surveillance tools in support of laboratory accreditation to ISO/IEC 17025.
