Heparin-Induced Thrombocytopenia: The Dark Side of a Common Anticoagulant
Heparin-induced thrombocytopenia (HIT) is a syndrome of platelet activation, thrombocytopenia, and thrombosis that occurs in 1-5% of patients who receive heparin. HIT is a clinicopathologic diagnosis where laboratory testing plays an essential role. Accurate and timely diagnosis is essential to avoid potentially life- or limb- threatening thrombotic complications. It is also important to avoid HIT over-diagnosis, which is common, and leads to suboptimal patient management. This presentation will emphasize the role of the laboratory in HIT diagnosis. At the conclusion, participants will be able to describe the syndrome, available laboratory testing, and optimal diagnostic algorithms.
Originally presented on December 19, 2016, in Salt Lake City, Utah.
