What’s Tested
Clotting is the body’s way of stopping bleeding, but if blood clots too quickly or slowly, it can lead to serious health concerns. As a laboratory, we offer the PT/INR test to provide you and your healthcare provider with critical information about your blood’s ability to form clots. This test is especially important for people taking blood-thinner medications (like warfarin/Coumadin), those with unexplained bleeding or clotting, or before certain surgeries. With clear and accurate results, your provider can adjust medications or recommend further treatment, helping you stay safe and healthy.
Major Components and Descriptions:
- PT (Prothrombin Time): Measures how many seconds it takes for your blood sample to form a clot.
- INR (International Normalized Ratio): Standardized ratio that lets your provider compare results from different labs, especially important for managing blood-thinner doses.
- aPTT (Activated Partial Thromboplastin Time): Often ordered together, this tests another pathway of blood clotting.
With reliable PT/INR results provided by our laboratory, you and your provider can spot clotting problems early and manage blood-thinner doses precisely, giving you peace of mind and better protection from serious bleeding or dangerous clots.
