Prothrombin Time (PT) with INR is a crucial blood test that measures how quickly your blood forms clots. It helps detect clotting disorders that can cause excessive bleeding or dangerous clot formation. The International Normalized Ratio (INR) standardizes PT results, making it easier to compare values across different labs. PT/INR testing is especially important for patients on blood thinners like warfarin, or for those undergoing surgery. Abnormal PT/INR levels can indicate liver disease, vitamin K deficiency, or inherited clotting factor issues. Regular monitoring of PT and INR ensures safer medical treatments and helps prevent life-threatening bleeding or clotting events.
