of blood thinning drugs by measuring the time taken for blood clots to form. A normal person not on anticoagulant therapy likely has an INR around 1. The INR test is done by drawing the patient's blood and having a reagent added to the blood, causing it to start clotting. The higher the INR score is, the longer it will take for the blood to clot. An INR score of 2.0 to 3.0 means the patient has basic 'blood thinning' needs, and for patients with a high risk of clots, the goal is to have an INR score of 2.5 to 3.5.
