What is PROTHROMBIN TIME (PT INR)?

The Prothrombin Time (PT) with INR (International Normalized Ratio) test measures how long it takes for your blood to clot. It assesses the function of several clotting factors in your blood. This test is crucial for evaluating your blood's clotting ability.

Why is this test important?

PT INR is widely used to monitor patients on anticoagulant medications like warfarin, ensuring their dosage is effective and safe. It also helps diagnose bleeding disorders, liver disease, and vitamin K deficiency, which can all affect blood clotting.

How to Prepare

Inform your doctor about any medications you are taking, especially blood thinners. No other special preparation is typically required.
