The registration period ended on 31 March. We are currently contacting those laboratories where a proficiency test cannot be performed (at all or optimally) due to a small number of participants and are discussing possible options.

The samples will be shipped in calendar week 18. During the same period we will provide access to our online portal which will provide all participants with technical information on their proficiency tests.

The test phase begins with the arrival of the samples. All participants have until 31 July to carry out the planned tests and submit the results to us via the portal.
