Research Progress on Cytometric Bead Assay for Platelet Antibody Detection / 中国实验血液学杂志

ABSTRACT

Anti-platelet specific antibody is one of the most important reasons leading to thrombocytopenia and megakaryocyte dysmaturity. The detection of platelet autoantibodies is an important step in the diagnosis of ITP because of the absence of specific clinic feature. The monoclonal antibody-specific immobilization of platelet antigens (MAIPA) has become a "gold standard" for determination of PLT specific antibody, which has high specificity and low sensitivity. However, this assay is time-consuming and tedious work. Routine use of this assay in hospital is difficult. Recently, some researches reporded the cytometric bead assay that has higher sensitivity than MAIPA, and so probably solves the problem of time-consuming partly, that also can use different beads for simultaneous detection. This review focuses on recent progress of the cytometric bead assay.
