Final answer:
INR is a test that measures blood clotting time and is used to monitor the effectiveness of anticoagulant medications. The normal INR range for a person not on medication is generally between 0.8 and 1.2.
Step-by-step explanation:
INR, or International Normalized Ratio, is a laboratory test that measures the time it takes for blood to clot. It is used to monitor the effectiveness of anticoagulant medications such as warfarin. The normal INR range for a person not on medication is generally considered to be between 0.8 and 1.2. An INR higher than the normal range indicates that the blood is taking longer to clot, while an INR lower than the normal range indicates that the blood is clotting too quickly. It's important to note that the target INR range may vary depending on the condition being treated and individual patient factors.
