Prothrombin Time with INR


The PT/INR test is a clinical tool used to assess blood clotting time, particularly for individuals on anticoagulant medication like warfarin. Symptoms prompting this test may include unexplained bleeding, easy bruising, or prolonged bleeding from minor cuts. The test measures the prothrombin time (PT) and international normalized ratio (INR), guiding healthcare providers in adjusting anticoagulant dosages. Regular monitoring ensures therapeutic anticoagulation levels, preventing excessive bleeding or clotting, and optimizing overall health outcomes for individuals on anticoagulant therapy.
