Utilizing two platelet antibody assay systems, flow cytometric analysis and a microcytotoxicity assay, it was possible to demonstrate for the first time platelet-directed antibody in the sera of three of six patients with primary thrombotic thrombocytopenic purpura. These results lend support for an immune-mediated pathologic process in some patients with this disorder.
