Getting Tested for Antithrombin Deficiency: What to Expect
Published: Dec 03, 2023
Testing for antithrombin deficiency can be daunting. Here's a breakdown of what to expect and how it can help you manage your health.
Why Get Tested?
Testing for antithrombin deficiency is important if you have a personal or family history of blood clots. It helps determine if your body has enough antithrombin to regulate blood clotting. Early detection can prevent severe complications by allowing for timely intervention and treatment adjustments.
Types of Tests
The primary test for diagnosing antithrombin deficiency is the antithrombin activity assay. This blood test measures how well your antithrombin is functioning. In some cases, genetic testing may also be conducted to identify mutations in the SERPINC1 gene that lead to inherited deficiency.
Interpreting Test Results
Test results showing low antithrombin activity may indicate a deficiency, but further evaluation is often required to distinguish between inherited and acquired causes. Consultation with a healthcare provider is crucial to understand the results and plan the next steps, which may include lifestyle changes or medication.
