Scan 4 Health Diagnostics offers the Anti Thrombin III (Antigenic) test, a precise and essential assay that measures the amount of antithrombin III protein in your blood. Antithrombin III is a natural anticoagulant produced by the liver that is crucial for preventing abnormal blood clots in blood vessels. By providing insight into your risk for excessive clotting (thrombosis) or bleeding disorders, this test helps guide diagnosis, monitor ongoing conditions, and assess the impact of therapies that affect coagulation. Scan 4 Health delivers trusted laboratory expertise, fast turnaround, and compassionate care with every test.

To ensure accuracy and safety:

• Fasting: No fasting is generally required unless other tests are performed at the same time; follow your healthcare provider's instructions.
• Medications: Many medicines can affect antithrombin III levels—especially blood thinners (anticoagulants) such as warfarin or heparin, or chemotherapy agents like asparaginase. Tell your doctor and laboratory staff about any current medications, supplements, or herbal products you are taking.
• Blood Collection: Wear a shirt with loose sleeves for easy access. Ensure you are well-hydrated for smoother sample collection.
• Special Preparation: Do not stop any medications unless instructed by your doctor. Never discontinue anticoagulants or other prescribed treatments without explicit guidance.
• Health Status: Inform staff if you have recently suffered an infection, surgery, trauma, or illness, as these can temporarily alter antithrombin levels.

A healthcare professional will collect a blood sample, usually from a vein in your arm, with only mild and brief discomfort.

This test checks how much antithrombin III protein is in your blood. Antithrombin III helps control blood clotting by binding to and inhibiting certain clotting proteins, preventing dangerous clots from forming. Low levels can happen because of a condition you are born with (which raises the risk of unusual blood clots or blood clots in deep veins) or because of other health problems like liver disease, kidney problems, serious blood clotting disorders, or taking certain medicines like heparin.

Conversely, some people have an adequate amount of antithrombin protein, but it does not function well (functional deficiency), requiring parallel activity measurements for a conclusive diagnosis. High antithrombin levels are less common but may indicate other rare conditions.

The test is recommended for:

• Patients with unexplained or recurrent episodes of clotting (thrombosis)
• Screening close relatives of individuals with confirmed antithrombin III deficiency
• Pre-surgical evaluation in high-risk patients
• Ongoing monitoring in patients using anticoagulants (heparin, warfarin)
• Clarifying abnormal clotting test results or suspected coagulation disorders
