Circulating antibodies to platelets have been associated with immune and drug-induced thrombocytopenia. Elevated levels of platelet - associated antibodies may occur in autoimmune thrombocytopenia, as well as thrombocytopenia associated with carcinoma, AIDS, and connective tissue diseases. Both circulating and associated platelet antibodies may play a role in platelet destruction. Platelet antibodies may consist of a single isotype or any combination of isotypes.
