Order of follow-up samples

Participants in our PT programs can order one extra vial per test sample, free of charge. If you require more than one vial of a sample you can order this via PT-micro@slv.se for a cost of 300 SEK per vial.

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. We only dispatch samples on Mondays-Tuesdays to avoid that the package is being stored at a post office over the weekend.


Please enter your laboratory number and which sample(s) you want to order.

Do you require shipping with courier? (1300 SEK)
