Inr Levels Definition. The inr is found using the results of the prothrombin time pt test. Patients who are on blood thinning medications typically have elevated inr levels between 2 and 3 5 according to the american association for clinical chemistry. Here is a brief simplified chart of human blood inr range showing inr levels and the factors that affect them. This measures the time it takes for your blood to clot.
Patients who are on blood thinning medications typically have elevated inr levels between 2 and 3 5 according to the american association for clinical chemistry. Patients with a tendency towards clotting may have a range targeting 3 4 whereas patients with a higher bleeding risk may have a lower inr between 2 2 5. The inr or international normalized ratio is a measure of how long it takes your blood to clot. This chart illustrates typical therapeutic inr levels while using coumadin warfarin therapy. A typical inr target ranges from 2 3 but can vary from patient to patient. An inr up to 10 is targeted in hyper therapeutic situations where any clotting at all absolutely must be avoided.

The inr is found using the results of the prothrombin time pt test. If you take blood thinners also called anti clotting medicines or anticoagulants it may be important to check your inr. The inr or international normalized ratio is a measure of how long it takes your blood to clot. A system established by the world health organization who and the international committee on thrombosis and hemostasis for reporting the results of blood coagulation clotting tests. The first step of the inr calculation is to normalize the pt by comparing it to the mean normal prothrombin time mnpt the geometric mean of the prothrombin times of the healthy adult population. If your inr is too low you could be at risk for a blood clot but if it s too high you could experience bleeding.
