Quality Control

Quality control is one of the most important steps in the manufacture of in vitro diagnostics. Take advantage of our many years of experience in the procurement of specific plasmas, the processing of negative plasma, and the stabilization of human raw materials. We offer the ideal prerequisites for procurement, processing, and testing. Why? All of our starting materials are tested negative for HIV, HCV and HBsAg.

We would be happy to offer you further tests upon request.
