Participation in proficiency testing enables laboratories to guarantee the quality of their results and demonstrate their competence in their fields of activity.
Cofrac provides its laboratories and their clients with a recently published ILAC brochure, The benefits of participating in PT, that sets out the benefits that can be enjoyed by all parties with an interest in accreditation: accreditation bodies, laboratories, professional federations, clients, ordering parties, public authorities, etc. We invite you to familiarise yourself with this document and help to circulate it as widely as possible.
