Anti-Thrombin III (Functional) Test

AT III Functional Assay

Antithrombin Activity Test

The Anti-Thrombin III (Functional) Test is a diagnostic blood test used to assess the functional activity of antithrombin III, a natural anticoagulant in the blood. This test helps in evaluating the risk of excessive blood clotting (thrombosis) and monitoring anticoagulant therapy.

The test is crucial for assessing the risk of thrombosis and monitoring the effectiveness of anticoagulant therapy.
Low levels of antithrombin III activity may predispose individuals to thrombotic events, while high levels may indicate an acquired deficiency.
Results should be interpreted by a hematologist or healthcare provider in the context of the patient's medical history and overall coagulation profile.

Test Parameters

1 - Antithrombin III Activity

The test measures the functional activity of antithrombin III, providing insights into the body's natural anticoagulant capacity.

Sample Collection

Blood samples are collected from the patient through standard venipuncture procedures.

Collection Method : Blood Collection

Turn Around Time : Results are typically available within a few days after the blood sample is collected.

Preparation

No specific preparation is usually required for this test. However, patients should follow any specific instructions provided by the healthcare provider, especially if they are on anticoagulant therapy.
