The antigen-specific assays currently used for the laboratory investigation of platelet antibodies and antigens are technically complex and cannot be used in most routine laboratories. Here, we describe a simple antigen-specific capture assay (ASCA) for the detection of serum platelet antibodies and for human platelet antigen-1a (HPA-1a) phenotyping. ⋯ In our opinion, the ASCA is easy to perform and much more sensitive than the currently available antigen-specific assays for the detection of platelet antibodies.
