[Application of microcolumn gel immunoassay in screening the platelet antibody].

The purpose of this study was to explore the clinical value of the platelet antibody screening and typing in platelets transfusion by using microcolumn gel immunoassay (MGIA). The platelets antigen-antibody reactions including the antibody screen and blood crossmatch were detected by MGIA. The results indicated that the detection of platelet antibody showed positive in 30 cases of aplastic anemia (AA), 11 cases of myelodysplastic syndrome (MDS), 24 out of 25 cases of leukemia and 1 out of cases of other diseases, while detection of platelet antibody showed negative in 20 normal volunteer donors.
