The sensitivity and specificity of platelet autoantibody testing in immune thrombocytopenia: a systematic review and meta‐analysis of a diagnostic test

Journal of Thrombosis and Haemostasis, 2019
Essentials The diagnosis of ITP is based on a platelet count < 100 × 109 L−1 and exclusion of other causes. There are no standard tests or biomarkers to diagnose ITP. The sensitivity of platelet autoantibody testing is low (53%). The specificity is high (
