![Effect of IVIG therapy on PLT count and procoagulant platelets. Platelet count increment (A) and procoagulant platelets after IVIG therapy (B-C). Procoagulant platelets (CD62P/Phosphatidylserine [PS]+) were analyzed in patients before and after IVIG therapy via Annexin V-FITC and CD62p-APC antibody staining.
