Additional Information

This test measures how long it takes for your blood to clot. It's used to monitor warfarin therapy (a blood thinner) in patients taking this medication to treat or prevent blood clots. The test can also help detect bleeding or clotting disorders. Results are presented as an INR (International Normalized Ratio), a standardized value consistent across labs. Abnormal results may indicate a need for medication adjustment or further investigation.
