ABSTRACT
This study was aimed to investigate the influence of different platelet membrane glycoprotein monoclonal antibodies (McAb) which are common used in laboratories on the monoclonal antibody-specific immobilization of platelet antigens (MAIPA) technique according to the request of 14th International Society of Blood Transfusion Platelet Immunology Workshop. 30 participant laboratories were provided with 10 known human platelet antigen (HPA) antibodies, 1 normal serum, 9 different McAbs (against GPIIb/IIIa, GPIa/IIa, GPIb/IX and GPIV respectively), and the same protocol. Each participant laboratory carried out the test as the protocol to compare the results of different McAbs against the same glycoprotein and submitted the data to organizer. The results indicated that in McAbs against GPIIb/IIIa, AP2, Gi-5 and PL2-73 showed higher mean S/CO than that of others; in GPIa/IIa, MBC202.2 and 143.1 showed higher mean S/CO than that of others; in GPIb/IX, 142.11 and CLB-MB45 (CD42b) showed higher mean S/CO than that of others; as to GPIV, 131.4 showed higher mean S/CO. In conclusion, capture effects of various McAbs are different, so that different products of McAbs exert influences on the sensitivity of MAIPA. To use a panel of McAbs against the same glycoprotein may avoid the false negative results.
