Yes, elevated PT/INR values require immediate attention.
1. Prothrombin time
(PT) is a blood test
that measures the time it takes for the liquid portion (plasma) of your blood to clot. Normally, it is 11 to 13.5 seconds.
2. The International Normalized Ratio (INR) is calculated from a PT results. INR of 1.1 or below is considered normal.
These two tests are used to monitor how well the blood-thinning medicine (anticoagulant
) Warfarin is working to prevent blood clots
An INR range of 2.0 to 3.0 is generally an effective therapeutic range for people taking Warfarin for disorders such as atrial fibrillation
or a blood clot in the leg or lung.
When the PT and INR are elevated, it means that your blood clots more slowly than desired and there is an increased risk of bleeding.
So, you need to consult your treating doctor, adjust the dose of 'blood thinner' so as to keep these tests within their normal range.
