Background: Neonatal alloimmune thrombocytopenia (NAIT) is one of the most common bleeding disorders in neonates. It occurs when alloantibodies from an immunized mother react with paternally inherited alloantigens, mostly human platelet antigen 1a (HPA-1a), on the fetal platelets (PLTs). Currently, monoclonal antibody-immobilized PLT antigen (MAIPA) assay represents the standard technique for the serologic diagnosis of NAIT.

We developed a simple particle agglutination test (PaGIA) for the detection of HAMAs.
Design And Methods: Red-dyed high density particles were coated with monoclonal mouse IgG.
A simple and rapid antigen-specific assay for the identification antibodies to platelets is lacking, yet. Red-dyed polystyrene microbeads were coated with monoclonal antibodies to various platelet glycoprotein complexes, and used for the detection of platelet autoantibodies and alloantibodies. The results were largely identical with those obtained by monoclonal antibody-specific immobilization of platelet antigen assay (MAIPA).
View Article and Find Full Text PDFBackground: The antigen-specific assays currently used for characterization of platelet (PLT)-reactive auto- and alloantibodies are too technically complex and impracticable for most routine laboratories. Here, a novel antigen-specific particle assay (ASPA) for PLTs similar to that of red blood cells is described.
Study Design And Methods: PLTs were solubilized and then incubated with red-dyed polystyrene particles coated with monoclonal antibodies (MoAbs) to various PLT glycoprotein complexes.
