At the MEDICA 2006 we will be presenting our new product line SERION Multianalyt™. This technology allows the simultaneous quantification of several analytes in one sample preparation. SERION Multianalyt™ is a platform independent method for multiplex diagnostics based on flow cytometry. Its universal applicability and its easy handling makes the test system an especially economic solution meeting the increasing requirements in the range of diagnostics. We are introducing four validated Multianalyt™ systems for the antibody diagnosis of Epstein-Barr-Viruses, Pertussis, Borrelia and different vaccination parameters (Diphtheria, Tetanus, Bordetella pertussis Toxin).
