About Prothrombin time (inr)

What is prothrombin?

Prothrombin is a protein produced by the liver that is important for blood clotting. Blood clotting (coagulation) is an essential process for preventing excessive bleeding after an injury.

A prothrombin time test measures the time it takes for your blood to clot. The internationalised normalised ratio (INR) standardises the results of a prothrombin time test results since different laboratories may use slightly different methods and reagents.

The INR is often used to monitor the effect of blood-thinning medications such as warfarin. A high INR is associated with a greater risk of bleeding, whilst a low INR is associated with a greater risk of clotting.  

Why take the test?

This test measures the speed of clotting using the standardised INR and can be used to monitor the effect of blood-thinning medications such as warfarin.
