What is a ANTI THROMBIN ACTIVITY, FUNCTIONAL?
Anti-Thrombin Activity, Functional is a blood test that measures the ability of antithrombin, a natural anticoagulant protein, to inhibit clotting factors and help prevent excessive blood clot formation. The test is needed to evaluate suspected antithrombin deficiency, particularly in individuals with unexplained or recurrent blood clots at a young age. It may also help investigate unusual thrombotic events or assess abnormal coagulation findings.

FAQs
Antithrombin is a protein produced mainly by the liver that naturally limits blood clotting by inhibiting important clotting factors, particularly thrombin and factor Xa.
Low activity may indicate reduced antithrombin function and can increase the risk of abnormal blood clot formation. Further testing may be required to determine the cause.
A normal result indicates that antithrombin is functioning within the laboratory's reference range at the time of testing.
Not necessarily. Deficiency can increase the risk of thrombosis, but whether a clot develops depends on several genetic and acquired risk factors.
Yes. Antithrombin deficiency can be inherited due to changes in the SERPINC1 gene. However, reduced antithrombin levels can also occur because of acquired medical conditions.
