In vitro Tests for Platelet Compatibility

Abstract
Four methods were investigated to determine their suitability as platelet compatibility procedures: leukoagglutination, lymphocytotoxicity, platelet suspension immunofluorescence and platelet enzyme‐linked immunosorbant assay. None of the tests were found to reliably predict the 24‐hour‐posttransfusion platelet increment in 8 refractory thrombocytopenic patients judged refractory to random donor platelet therapy.
