Description
Citrate plasma, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
Blood sample drawn from a vein, usually from the arm.
Test Time:
The test is usually completed within a few hours to a day.
Test Normal Range:Â
The normal range of anti thrombin III activity is typically between 80% and 120% of the average level found in healthy individuals.
What is the Test?
The Anti Thrombin III Activity test measures the functional activity of anti thrombin III, a natural anticoagulant protein in the blood. Anti thrombin III plays a crucial role in regulating blood clotting and preventing excessive clot formation.
Test Procedure:
Blood must be drawn from a vein in your arm for the test. The sample is then processed in a laboratory to measure the functional activity of anti thrombin III.
When to Take the Test:Â
The test is ordered to evaluate the risk of excessive blood clotting (thrombosis) or to monitor the effectiveness of anti-coagulation treatment, such as heparin therapy.
Who Should Take This Test:
Individuals with a history of blood clotting disorders, a family history of thrombosis, or those undergoing anti-coagulation treatment may need this test.
Precautions for Exceptional Cases (Pregnancy etc.):
Pregnant individuals or those who have recently undergone surgery should inform their healthcare provider before the test, as these conditions can affect anti thrombin III levels.
