Test Information:
Antithrombin III is the plasmatic inhibitor of thrombin and activated factor X and forms an irreversible inactive complex with these enzymes. This test aids in the quick determination of physiologically active AT III and allows the diagnosis of inherited and acquired antithrombin III deficiency, which represents an increased risk of thrombosis.
