About the Prothrombin Test: Prothrombin Time PT with INR
The prothrombin time test measures how long blood takes to clot through the extrinsic and common clotting pathways, and the result is usually reported with the International Normalized Ratio (INR) so it can be compared across laboratories. The activated partial thromboplastin time (aPTT) may be included to assess the intrinsic pathway. Together these tests evaluate clotting function, help monitor anticoagulant therapy such as warfarin, and investigate unexplained bleeding or clotting.
Who this test may be right for
- People taking warfarin or similar anticoagulants being monitored
- Individuals with unexplained bleeding or bruising
- Patients with suspected clotting disorders
- People with liver disease affecting clotting factor production
- Patients being assessed before surgery or procedures
What this test measures
- Prothrombin Time (PT) Measures the time in seconds for blood to clot via the extrinsic and common pathways.
- International Normalized Ratio (INR) A standardized ratio derived from PT that allows comparison across laboratories, especially for warfarin monitoring.
- Activated Partial Thromboplastin Time (aPTT) Measures the intrinsic and common pathways when included in the panel.
Before your visit
- Report all anticoagulant and other medications, especially warfarin
- Avoid alcohol excess and major dietary changes before testing unless advised
- No fasting is usually required
- Collect at the time recommended for therapy monitoring
Understanding your results
A prolonged PT or high INR can indicate a bleeding tendency or the effect of anticoagulant therapy, while a short PT is less commonly significant. The aPTT helps localize clotting problems to different pathways. Results are interpreted with your medications, liver function, and clinical situation. Discuss your PT, INR, and aPTT results and any changes to therapy with a healthcare provider.
