Private INR Blood Test

What Is an INR Test?

An INR (International Normalised Ratio) test measures how long it takes your blood to clot. It’s primarily used to monitor people taking warfarin or other anticoagulant medications to ensure their dosage is both safe and effective. Maintaining the correct INR range helps reduce the risk of excessive bleeding or dangerous clots.

Why Is the INR Test Important?

If you're on blood thinners, even slight variations in clotting time can have serious consequences. An INR test helps healthcare providers determine whether your medication needs to be adjusted. It is a key tool in managing conditions like atrial fibrillation, deep vein thrombosis or artificial heart valves.

Who Should Consider an INR Test?

You may need this test if you:

• Are currently prescribed warfarin or similar blood thinners
• Have a history of blood clots or stroke
• Have a heart condition such as atrial fibrillation
• Have a mechanical heart valve
• Need to monitor how a medication is affecting blood clotting

What’s Included in the INR Test?

This test measures your INR level through a small blood sample. Your result will indicate whether your blood is clotting within a safe range or if medication adjustments may be required.
