The prothrombin test measures how long it takes your blood to clot. It is often ordered to check for bleeding disorders, monitor blood-thinning medications, or assess liver function.
What it measures
- Prothrombin Time (PT) — The time in seconds for a clot to form.
- International Normalized Ratio (INR) — A standardized ratio that allows comparison across labs.
- Prothrombin Activity — A percentage showing how well your clotting factors work.
- Fibrinogen — A protein that helps form clots; sometimes measured with PT.
Who it is for
A doctor may order this test if you have unexplained bleeding or bruising, or if you take warfarin or another blood thinner. It is also used before surgery or to monitor liver disease.
Preparation
No fasting is needed for a prothrombin test. Tell your doctor about all medications, especially blood thinners, as they can affect results.
Results and what they mean
Results are reported as seconds for PT and as a number for INR, along with a reference range. Your clinician interprets these values based on your health and medications. This is general information, not medical advice; discuss your results with a healthcare professional.
