Antithrombin

The Antithrombin blood test measures the level and activity of antithrombin, a protein that helps regulate blood clotting. Antithrombin inhibits the activity of clotting factors, preventing excessive clot formation.

Sample Type: The test requires a small blood sample, typically obtained by drawing blood from a vein in your arm using a needle.

Normal Range: The normal range for antithrombin levels can vary depending on the specific laboratory and the reference values they use. Generally, the normal range is around 80 to 120% activity.

Antithrombin deficiencies can be hereditary or acquired. Hereditary deficiencies are usually present from birth and can increase the risk of abnormal blood clotting, such as deep vein thrombosis (DVT) or pulmonary embolism. Acquired deficiencies can occur due to liver disease, kidney disease, certain medications, or other underlying health conditions.

The Antithrombin blood test measures the level and activity of antithrombin to assess its functioning in the blood clotting process. If the level or activity of antithrombin is below the normal range, it may indicate a deficiency, and further evaluation may be needed to determine the underlying cause and appropriate management.

It’s important to consult with a healthcare professional for proper interpretation of your Antithrombin test results and to discuss any necessary steps or treatments based on the findings, especially if you have a personal or family history of blood clotting disorders.
