Antithrombin deficiency is a blood disorder characterized by the tendency to form clots in the arteries and/or veins (thrombosis). An inherited tendency to thrombosis is known as thrombophilia. Antithrombin is a substance in the blood that limits the blood's ability to clot (coagulate). In people with congenital antithrombin deficiency, there is usually a reduced amount of this substance in the blood due to a genetic abnormality. Antithrombin deficiency may also be acquired; in such cases, the disorder may be reversible with treatment.
