Shop - ProthrombinTime (PT with INR)

Prothrombin Time (PT with INR) is a blood test that evaluates the clotting ability of blood by measuring the time it takes for a blood sample to clot. The test specifically assesses the function of various clotting factors produced by the liver. The International Normalized Ratio (INR) is a standardized measure derived from the PT, allowing for consistent interpretation of results regardless of the testing methods used by different laboratories. This test is commonly used to monitor patients on anticoagulant therapy (such as warfarin), assess liver function, and diagnose clotting disorders. Abnormal PT/INR results may indicate bleeding disorders, liver disease, or vitamin K deficiency.
