I Take Coumadin® (Warfarin)

If you take Coumadin® (the generic name is warfarin), it's very important to measure your blood's anti-coagulation level on a regular basis. That's what the PT/INR test is for. By keeping your PT/INR in a safe range, you can avoid many serious complications like stroke and bleeding.

Your doctor is probably checking your PT/INR level in his or her office or sending you to a local lab about once a month, but now you can check your own PT/INR in the comfort of your own home. This is called PT/INR self testing.

  • Fast. Accurate. Easy-to-use.
  • Covered by Medicare and most insurance providers.
  • Clinically proven to reduce stroke and bleeding.

With self testing, you check your PT/INR level once a week, which means your doctor will find out more quickly if your blood's anti-coagulation level is out of the safe range (also known as the "therapeutic range"). Clinical studies have shown more frequent testing lowers the risk of serious complications.

Medicare and many insurance plans cover weekly PT/INR self testing for most patients taking Coumadin® (warfarin) — so it probably won't cost you any more to enjoy the convenience and accuracy of self testing.

You'll need a prescription from your doctor to begin PT/INR self testing at home. Ask your doctor if self testing is right for you!
