Synonym: immune thrombocytopenic purpura
Immune thrombocytopenia (ITP) describes an autoimmune disorder in which the number of circulating platelets is reduced. This is due to their increased destruction, and sometimes also due to reduced production. ITP was previously known as idiopathic thrombocytopenic purpura but this is outdated, now that it is known to have an autoimmune cause.
