Available test items

For follow-up examinations or also for internal quality assurance, it is possible after the proficiency tests have been carried out, to get residual quantities of the remaining test items. Please note that no further stability tests are performed on these materials. The content data and statistical parameters are therefore derived exclusively from the results of the associated comparative laboratory test. Information about the contents of the sample parameters can only be taken from the corresponding evaluation protocols. Therefore, laboratories that were not themselves participants in the corresponding proficiency test additionally require the associated evaluation as a PDF file at a price of 30.00 Euro.

Since November 2019 our online shop for test items  is available for a more comfortable ordering.
