What is the normal range for INR results in adults?

The normal range for INR (International Normalized Ratio) results in adults is indeed between 0.9 and 1.2. This metric is crucial for monitoring individuals on anticoagulant therapy, as it helps gauge blood clotting function. A normal INR indicates that the blood clotting system is functioning within a typical range, which is important for preventing excessive bleeding or thromboembolic events.

When a patient is on anticoagulation medications like warfarin, healthcare providers monitor INR levels to ensure they stay within a safe and therapeutic range. An INR lower than the normal range may suggest a risk for clot formation, while an INR significantly higher than this range indicates a risk of bleeding.

Other ranges, such as those provided in the other choices, reflect either lower levels which do not effectively monitor anticoagulation therapy or higher therapeutic targets that are specifically used in clinical settings for patients at risk of thromboembolic events, but are not considered normal for general adult populations. Therefore, understanding the normal INR range is pivotal for safe patient management.
