血小板抗體篩檢及同時進行血小板交叉配對之免疫檢驗方法及檢測裝置

This invention provides an immunoassay method and detection device for platelet antibody screening simultaneously with platelet cross-pairing. Several different platelet antigen type combinations are selected according to the type frequencies of human leukocyte antigens and human platelet antigens and are mixed to prepare a combined reagent for screening antibody; in addition, individuals of randomly selected platelet blood products are subjected to a cross-pairing test at the same time, and then the platelet antigens and serums forming an immune complex are directly subjected to a cleaning program with high retention efficiency by virtue of an interception device, and finally, a signal calibration reagent is added, the platelet antigens and serums forming the immune complex can form a final product together with the signal calibration reagent; and due to the detection of the final product, the existence of a platelet antibody may be determined, and meanwhile, individual platelet blood products which are consistently infused are determined, so that the test efficiency is increased.
