Service Providers for Prothrombin Time (INR)
The Prothrombin Time (INR) test measures blood clotting time, assessing how well blood clots in response to certain medications or conditions. Preparation typically involves fasting for 8–12 hours. During the test, a blood sample is drawn from a vein, usually in the arm. Risks include minor bruising, bleeding, or fainting. Results show clotting time, with a higher INR indicating slower clotting, often linked to anticoagulant use or liver disease. Conditions like liver disorders, vitamin K deficiency, or blood clotting disorders may affect results. INR values help monitor patients on blood thinners like warfarin.
