Heparin-induced thrombocytopenia (HIT) is the development of thrombocytopenia (a low platelet count) due to the administration of various forms of heparin an anticoagulant. HIT predisposes to thrombosis the abnormal formation of blood clots inside a blood vessel and when thrombosis is identified the condition is called heparin-induced thrombocytopenia and thrombosis (HITT). HIT is caused by the formation of abnormal antibodies that activate platelets.
