  1. Mild thrombocytopenia: >50 × 109⁄L, moderate thrombocytopenia: 30 × 109–50 × 109⁄L, severe thrombocytopenia: 10 × 109–30 × 109⁄L, very severe thrombocytopenia: <10 × 109⁄L, minimum platelet count: minimum platelet count during clinical course, Severe ITP is defined by the presence of clinical significant bleeding symptoms at presentation sufficient to mandate treatment, ITP immune thrombocytopenia
