Proficiency testing - Microbiology

Tre vialer

Laboratories can objectively prove their analytical skills by participation in proficiency testing (PT) programs.

PT programs

The Swedish Food Agency has arranged proficiency testing programs for microbiology since 1981. The programs are approved by SWEDAC, the accreditation body in Sweden, according to SS-EN ISO-IEC 17025 and SS-EN ISO-IEC 17043.

How a PT round works

  • Samples are sent out to laboratories that have registered for participation.
  • After analysis, participants report their results before a deadline.
  • The results are statistically analyzed and put together into a report which is published on the website.

(Results from PT rounds before March/April 2024 are available in our old web portal: https://www2.slv.se/absint.)

PT participants can order one extra vial of each samples, free of charge. Additional vials cost 504 SEK/vial.

Orders are placed in our web portal, on the same page for regular RM orders:

  • A fee of 410 SEK för administration/transport is added to each order.
  • When stored corrently (darkness and at least -20 °C, but not lower than -55 °C), the concentration of microorganisms in the PT samples are normally stable for one year after the PT round. A gradual decrease of the microorganisms is expected over time, but this will normally not have a significant effect on the outcome of the follow-up analysis.
  • Dispatch of samples is made within 1-2 weeks from ordering.
