title: Serological screening, using three different test systems of platelet-transfused patients with hematologic-oncologic disorders.
abstract: Sera of hematologic-oncologic patients were tested regularly after platelet transfusions in three test systems: lymphocytotoxicity test, platelet adhesion immunofluorescence test, and--only selected sera--in the monoclonal antibody-specific immobilization of platelet antigen test. Of 388 patients 53 (14%) had HLA antibodies 5 of these in combination with platelet-specific alloantibodies. Lymphocyte-restricted (non-HLA) reactions were observed in 20 patients, the majority of which was attributed to lymphocyte-specific auto- or alloantibodies. Sera of 27 patients showed platelet-specific reactions, usually cold-reacting autoantibodies which have no effect in vivo.
