In healthy people an INR of 1.1 or below is considered normal. 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. In certain situations, such as having a mechanical heart valve, you might need a slightly higher INR.
For normal patients (patients not on anticoagulant therapy) with present patient PT/control ratio equal to 1:0, the INR value is also going to equal 1.0 regardless of the ISI or the particular performing laboratory. Properly anticoagulated patients INR values will range between 2.0-3.0.
