FAQs About
INR Testing
and Warfarin

INR stands for International Normalized Ratio. It is a standardized measure of how long it takes your blood to clot. People who take anticoagulant medications, such as warfarin, need regular INR testing to ensure their level stays within the target range established by their physician.

INR testing helps determine whether your blood is clotting normally and whether your current warfarin dose is working effectively. If your INR falls outside the recommended range, your healthcare provider may adjust your dose.

Be sure to tell your provider about any other medicines or supplements you are taking, as some can affect your INR. Other factors that may influence INR results include (but are not limited to):

• alcohol
• foods high in vitamin K, such as green leafy vegetables
• soybean and canola oils
• high‑fat diets

Ask your doctor or nurse if there is anything you should avoid before your INR test.

To interpret your INR results, your provider will consider your symptoms, medical history, and any other relevant blood test results.

INR testing should be performed as often as your physician prescribes. Your healthcare provider will monitor your INR results and adjust your warfarin dosage as needed.
