Thank you for posting your query.

PT/INR test is an important test to determine the exact dose needed to maintain adequate anticoagulation.

A higher INR indicates more than normal blood thinning, and may increase the chance of bleeding.

A lower INR indicates inadequate blood thinning, and may predispose to clotting of blood.

The best time to take anticoagulant is in the evenings, and the best time to do the INR is in the morning.

There are several chances of error in this report, such as use of any other medications, change of diet, laboratory errors, such as delay in doing the test, etc.

Best wishes,

Dr Sudhir Kumar MD DM (Neurology)
