Abstract:

Introduction: Proficiency Testing/Interlaboratory Comparisons play an important role that is widely accepted in demonstrating the validity of results of any laboratory and inspection body. To ensure a coherent approach in the field within an economy, accreditation bodies develop specific policies for laboratories and inspection bodies’ participation in proficiency testing/interlaboratory comparisons. Methods: 39 Proficiency Testing/Interlaboratory Comparisons policies of accreditation bodies were reviewed for key requirements: initial accreditation, participations of accreditation per accreditation cycle and acceptance criteria of PT/ILC providers. Results: Within the analyzed policies a wide range of approaches was identified especially for the number of participations and acceptance criteria set by different bodies Conclusions: Even though the analyzed policies belong to accreditation bodies which are signatories of the same regional agreement, there is no harmonized approach with respect to Proficiency Testing/Interlaboratory Comparisons usage in the accreditation process

Keywords: accreditation, interlaboratory comparisons, medical laboratory, proficiency testing, quality assurance
