Introduction

Immune thrombocytopenia (ITP) is characterized by isolated thrombocytopenia with increased risks of bleeding.[1] Although severe thrombocytopenia is an important predictor of major bleeding,[2] bleeding severity inconsistently correlates with platelet count. Several factors have been shown to be associated with bleeding severity in ITP patients. These include platelet activation markers,[3] immature platelet fraction, and thromboelastometry.[4] The varying degrees of plasma thrombin generation may explain the bleeding heterogeneity found in ITP population. Thrombin generation test (TGT) has been reported to predict bleeding in certain bleeding disorders[5] [6] [7] and surgery.[8] This study aims to explore the TGT variables in primary ITP patients compared with healthy controls and their associations with bleeding symptoms.
