July 3, 2023The APTT (Activated Partial Thromboplastin Time) blood test measures the time it takes for blood to clot. It is used to assess the functioning of the intrinsic and common coagulation pathways.
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 APTT can vary depending on the specific laboratory and the reference values they use. Generally, the normal range is around 25 to 35 seconds.
The APTT test helps evaluate the efficiency of clotting factors involved in the intrinsic pathway of the blood coagulation process. It is commonly used to monitor the effectiveness of anticoagulant therapy (such as heparin), assess bleeding disorders, or investigate the cause of abnormal bleeding or clotting.
If the APTT result falls outside the normal range, it may indicate an issue with the blood’s ability to clot, and further investigation may be needed to determine the underlying cause. Additionally, the APTT test is often interpreted alongside other clotting tests to get a comprehensive evaluation of coagulation function.
It’s important to consult with a healthcare professional for proper interpretation of your APTT test results and to discuss any necessary steps or treatments based on the findings.
