Quality Assessment Scheme (QAS)

Our quality assessment scheme has been established in 1996 due to the fact that no standardization is available for the acetylcholine receptor antibodies.

The assessment scheme runs two times per year. With each trial four samples with different concentrations are provided. Each participant sends back quantitative and qualitative results. The participation in this scheme is free of charge and of course the results are handled confidentially.
