Prothrombin Time Test in Delhi

PT/INR testing is ordered for:

• Monitoring patients taking the blood thinner warfarin
• Before surgery, to assess bleeding risk
• Investigating unexplained bleeding, bruising, or blood in urine or stool
• Assessing liver function, since clotting factors are produced in the liver
• Evaluating vitamin K status

This test is used to monitor or diagnose:

• Bleeding disorders affecting clotting factor production
• Liver disease, since the liver produces most clotting factors
• Vitamin K deficiency
• Effectiveness and safety of warfarin therapy

1. No fasting is required for this test.
2. Inform the lab about all medications you're taking, especially any blood thinners, as this is essential for accurate interpretation.
3. If you're on warfarin, try to have this test done at a consistent time relative to your medication dosing, as advised by your doctor.

For patients on warfarin, the target INR range is specifically tailored to their condition, and your doctor will adjust your medication dose based on where your INR falls relative to this personalized target.
