Proficiency testing - Microbiology
Laboratories can objectively prove their analytical skills by participation in proficiency testing (PT) programs.
PT programs
The National Food Agency has arranged proficiency testing programs for microbiology since 1981. The programs are approved by SWEDAC, the accreditation facility in Sweden, according to SS-EN ISO-IEC 17025 and SS-EN ISO-IEC 17043.

How a PT round works
Samples that have been tested for homogeneity are sent out to laboratories that have registered for participation. After analysis, the participating laboratories report their results before a deadline.
The results are then statistically analyzed and put together into a report which is published on the website.
