What is the Prothrombin Time (PT) / INR Test?

The Prothrombin Time (PT) test measures how long it takes for your blood to clot. The result is usually expressed as an INR (International Normalised Ratio), which is a standardised value that makes results comparable across different laboratories. This test is essential for evaluating bleeding and clotting disorders.

Why is the PT / INR Test Done?

To monitor patients taking blood-thinning medication (anticoagulants) such as Warfarin — ensuring the dose is safe and effective
To investigate unexplained bleeding, bruising, or slow wound healing
To assess liver function, as the liver produces the clotting factors measured by this test
Before surgery, to check if blood clotting is normal
To diagnose clotting disorders such as haemophilia or vitamin K deficiency

Normal PT / INR Levels

Group	Normal Range
General population (not on anticoagulants)	INR: 0.8 – 1.2 \| PT: 11 – 13.5 seconds
Patients on Warfarin therapy (general)	INR: 2.0 – 3.0 (target range)
Patients with mechanical heart valves	INR: 2.5 – 3.5 (target range)

A high INR means blood is taking longer to clot, which increases bleeding risk. A low INR means blood may clot too quickly, increasing clot risk. Target INR depends on the reason for anticoagulation.

How to Prepare for the PT / INR Test

Fasting is not usually required for this test
Do not stop any blood-thinning medication before the test — the test is designed to monitor your levels while on medication
Inform the lab about all medicines you take, especially Warfarin, Heparin, Aspirin, or any anticoagulants
Avoid alcohol before the test if possible, as it can affect clotting results
If you have liver disease, a bleeding disorder, or recent surgery, inform the lab beforehand
