CoaguChek Patient Why Test FAQ Icon

Is an at-home meter as accurate as a test at my doctor’s office?

When you test at home with a CoaguChek® XS meter, you’re most likely using the same device most doctors use in their offices. A study has shown that the CoaguChek XS meter provides consistent results (97% correlation), whether through self-testing by trained users, or when the test is performed by a healthcare professional.1 That means you can count on reliable results without making a trip to your doctor’s office.

Are the CoaguChek XS meter and supplies covered by insurance or Medicare?

If you have a mechanical heart valve, chronic atrial fibrillation or venous thromboembolism and you’re on long-term warfarin therapy, Medicare Part B may cover meter training, services, equipment and supplies for monitoring your INR at home with a portable handheld meter.2 Most private insurance companies also cover INR self-testing.3 Individual plans vary, so it’s important to talk to your provider to find out if you’re covered. (Coverage varies based on your condition and other factors.)

Is it easy to learn how to perform a self-test?

It’s easy, thanks to our certified training. A certified healthcare professional will sit down with you at home or in your doctor’s office to provide step-by-step instruction on running a test and reporting the results.

What if I’m uncomfortable drawing my own blood sample?

Don’t worry – self-testing is very different from a lab testing. Instead of drawing blood from a vein in your arm, you simply stick your finger with a specially designed device. Once a small drop of blood appears, you apply it to a disposable test strip inserted in an easy-to-use, handheld meter. In about a minute, you have the result. In fact, most people who try self-testing prefer it to lab testing.4

Does it hurt to get a blood sample?

Getting a blood sample takes just a small fingerstick. A specially designed lancing device, which looks like a pen, quickly inserts a tiny needle and pulls it out again. You can even set the lancing device to go no deeper than necessary. Most people who try self-testing prefer it to lab testing.4

How can I make it easier to get a drop of blood?

Try these tips:

•  Warm your hand by holding it under your arm.

•  Use a hand warmer.

•  Wash your hands in warm, soapy water, and then rinse and dry thoroughly before testing.

•  Gently shake your arm down at your side for about 30 seconds.

•  Watch this video to learn how easy it is.
