Available test items

For follow-up examinations or internal quality assurance, residual quantities of the test items used can be purchased after a proficiency test has been carried out. Please note that no further stability tests are performed on these materials. The content data and statistical parameters therefore come exclusively from the results of the associated proficiency test. Information about the contents of the sample parameters can only be found in the corresponding evaluation reports. Laboratories that did not take part in the proficiency test in question therefore also need the associated evaluation as a PDF file, at a price of 50.00 euros.

You can conveniently order the test items in our Material Shop (available in German).
