The benefits of INR self-testing

Make the right choice for you when it comes to coagulation monitoring.

It is important to keep your blood’s clotting time within the range prescribed by your doctor. You may need to take your anticoagulant for a few weeks, months or even for the rest of your life. But no matter how long, your levels need to be regularly measured and that’s where INR self-testing is a great benefit.

Have the peace of mind that you know your INR value when needed, home or away. Self-monitoring only requires a drop of blood and results are available in about a minute.1 Results can either be reported to your doctor or nurse who will adjust your vitamin K antagonist dose for you, or you can learn how to adjust the dose yourself.
