| Antithrombin III (ATH III) is a plasma protein synthesized in the liver. Normal plasma levels are 115 to 160mg/L. ATH III consists of a single polypeptide chain and has a molecular weight of 58kDa. ATH III is a serine protease inhibitor and regulates coagulation by the formation of covalently liked complexes. ATH III also has a heparin binding site and in the presence of heparin the inhibition of thrombin, factors IXa, Xa and XIa is enhanced 1000 fold. Low levels of ATH III (functional or concentration) are associated with deep vein thrombosis and pulmonary embolism. Antithrombin assays are based on immunologic, enzymatic, or clotting properties |
