We produce in excess of 250,000 test materials, which are distributed to more than 150 countries around the world. PT is often referred to as external quality assessment (EQA) especially in the medical/clinical arena. Proficiency testing is a key element in the laboratory accreditation process, alongside reference materials, enabling laboratories to monitor the quality of their analytical results as stipulated in ISO/IEC 17025.
