Platelet Antibodies, Indirect (IgG, IgM) - The identification of circulating platelet antibodies is useful in order to identify immune-mediated platelet destruction. Disorders associated with immune platelet destruction include isoimmune neonatal thrombocytopenia, drug induced thrombocytopenia, drug sensitivities, allergies and post transfusion purpura. The destruction is either congenital, i.e., autoimmune where a malfunction in the immune response results in the production of antibodies directed against 'self' platelet specific antigens; or else platelet destruction occurs when the patient received platelet-specific antibodies from an ...
