Understanding PT INR (Prothrombin Time) in Lucknow

What is PT INR (Prothrombin Time) in Lucknow?

PT INR (Prothrombin Time) test is performed to estimate blood’s ability to clot and is available at an affordable price in Lucknow with Tata 1mg labs. It is used to diagnose bleeding or clotting disorders and to check the efficacy of any ongoing anticoagulant medication. Usually, this test is also advised before any surgical procedure.

The international normalized ratio (INR) is calculated from a prothrombin time (PT) result and is used to monitor how effectively blood-thinning medication is working to prevent blood clots. Higher-than-normal values indicate that blood takes a longer time to clot, whereas values lower-than-normal could indicate a clotting disorder where blood takes less time to clot.
