Plasma with high antithrombin level

Minimize test time. Ready to use.

Previously called antithrombin III (abbreviated ATIII), human antithrombin is one of the major physiological inhibitors of coagulation. A natural serine protease inhibitor, antithrombin acts mainly on thrombin (IIa) and activated Factor X (FXa), as well as on activated forms of factors IX, XI and XII. This reaction is catalyzed by heparin. The normal level of antithrombin is between 80 and 120% in adults and it is about half in newborns. Antithrombin deficiency predisposes to thrombosis.
