Heparin Antibodies

The Heparin Antibodies test is designed to measure the presence of antibodies against heparin in the bloodstream. Clinicians typically order this test when they suspect a patient has developed heparin-induced thrombocytopenia (HIT), a condition where the use of heparin, a common blood thinner, leads to a decrease in platelet count and an increased risk of thrombosis. This diagnostic test is particularly useful in patients who are undergoing treatment with heparin and present with an unexplained drop in platelet levels or thrombosis. By identifying the presence of these antibodies, the Heparin Antibodies test helps guide treatment decisions and manage patient safety effectively.
