“Idiopathic thrombocytopenic purpura (ITP) is the condition of having a low platelet count (thrombocytopenia) of no known cause (idiopathic).  Although most cases are asymptomatic, very low platelet counts can lead to a bleeding.Detection of antiplatelet antibodies in the blood is considered to confirm the diagnosis of ITP.[1] Treatment should be restricted to those patients with moderate or severe thrombocytopenia who are bleeding or at risk of bleeding. It should be limited in duration unless demonstrated that symptomatic thrombocytopenia persists. Patients with mild, asymptomatic thrombocytopenia, discovered incidentally on a routine blood count, should not be treated.”.
