| Expected TAT | 3-5 Days |
| Clinical Use | The platelet autoantibody study is designed to detect platelet autoantibodies eluted from the patient’s platelets or circulating in the patient's serum or plasma directed against GPIIb/IIIa, GPIb/IX, and GPIa/IIa. These antibodies can be detected in patients with autoimmune thrombocytopenic purpura (ITP or AITP). This test is intended to help identify patients who present with unexplained thrombocytopenia that is secondary to immune destruction. A positive test is considered diagnostic, while a negative test does not rule out the diagnosis. Repeat testing can sometimes be of benefit. |
