[Optical immunofluorescence detection of alloantibodies as a supplement to classical crossmatching within the scope of organ transplantation].

The importance of the indirect immunofluorescence test in evaluating an alloantigen-sensitization in organ transplantation is examined. In some antigen-antibody combinations, which are non reactive in standard complement dependent microlymphocytotoxicity assay there is seen a highly positive reaction in the indirect immunofluorescence test. Therefore this test is an important supplementation in the compatibility-definition in organ transplantation.
