frequently asked questions about coaguchek patient services
CoaguChek Patient Why Test FAQ Icon

What is coagulation?

Coagulation is the formation of blood clots inside the body. Proteins in the blood, called fibrins, and small elements in the blood, called platelets, work together to form a clot, which helps stop bleeding when you have a cut or injury.

What are anticoagulants?

Oral anticoagulants (blood thinners) such as warfarin or Coumadin® are drugs that help thin the blood of patients with conditions such as atrial fibrillation, thrombophilia and other diseases that increase the risk of forming blood clots. Patients taking warfarin have to sometimes make a lifelong commitment to this medication to avoid complications such as stroke or pulmonary embolism (blockage in the main lung artery).

These drugs are called vitamin K antagonists, and each patient reacts to them differently. There are also external factors that could interfere with the medication, including certain foods, stress and alcohol. That is why it is so important for anticoagulation patients to test according to a prescribed testing frequency.1

Why do I need warfarin?

For some people, blood clots form too easily or they don’t dissolve properly. These clots can impede blood flowing through the body, potentially leading to heart attack or stroke.2 Anticoagulation medication, such as Coumadin® or another brand of warfarin, slows down the clotting process to help keep you in a safe range.

What is PT/INR?

PT stands for “prothrombin time,” or the time it takes for blood to clot. INR is short for “international normalized ratio.” This is a calculation for standardizing results from PT tests. Essentially, PT/INR is a measure of whether your blood is clotting at a safe rate. You may see this referred to as PT monitoring, INR monitoring, or PT/INR.

What are the benefits of self-testing?

Checking your INR at home offers you:

Convenience

Check your own INR at home per your doctor’s prescriped test frequency on your own schedule, and never worry about missing a test.

Consistency

Use the same CoaguChek XS technology your doctor most likely uses to ensure results that are just as accurate as an in-office test.

More time in your target range

Self-monitoring per your doctor’s prescribed test frequency allows your doctor to make timely dosage adjustments, which may result in more time in range.3,10

Peace of mind

Being able to test where and when you need to enables you to test as prescribed.

Is an at-home meter as accurate as a lab test?

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.4 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.5 Most private insurance companies also cover INR self-testing.6 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.)

What’s the target range for INR levels?

The goal of monitoring your warfarin dose is to remain in the target range recommended by your doctor. For most people, a result of 2.0 to 3.0 is appropriate, although those at higher risk of clotting may have a target range of 2.5 to 3.5.7 Talk to your doctor about the appropriate range for you.

What if my results are out of range?

If your INR is higher than the target range, blood clots may not form quickly enough, and you may experience bruising or be at increased risk of bleeding. If your PT/INR is too low, you may still be at risk of excessive clotting.7 Talk to your doctor about the appropriate range for you.

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 instructions for running a test and reporting the results.

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

Don’t worry – self-testing is quite different from lab testing. Instead of drawing blood from a vein in the bend of your elbow, 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 approximately one minute, you have the result. Most people who try self-testing prefer it to lab testing.8

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.8

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.

What can affect my INR level?

Many things can alter your INR, including stress, missing a warfarin dose, taking herbal supplements and other medications, and consuming certain foods and beverages, such as kale and cranberry juice.9

Can I drink alcohol while taking warfarin/Coumadin®?

Alcohol can increase the effect of warfarin and further slow your clotting rate, causing your INR to be too high. You may want to avoid it while on warfarin.10

What’s the importance of vitamin K?

Warfarin works by blocking the body’s ability to use vitamin K, a necessary component in the formation of blood clots. When you’re taking warfarin, it’s important to keep the amount of vitamin K in your diet consistent, or it may impact the effectiveness of your warfarin dose.9

What foods are high in vitamin K?

Green vegetables such as spinach, kale and broccoli are high in vitamin K,9 as are the following foods:

• Tuna

• Prunes

• Green tea

• Beef and chicken liver

• Liverwurst

• Blueberries and blackberries 

How often should I test?

Test frequency should be determined by your healthcare provider.

What should I do with my used lancets?

Lancets are considered “medical sharps” and must be disposed of properly so they don’t injure sanitation workers and others. Guidelines vary by state, and many areas have collection programs for these items. Please visit the Coalition for Safe Community Needle Disposal site to find out what’s required in your state.

What health conditions require INR testing?

Any condition that results in an increased risk for blood clots and is treated with warfarin (sometimes known as Coumadin® or other brand names) will require regular testing. These include:

• Atrial fibrillation – The most common type of arrhythmia or irregular heartbeat.

• Venous thromboembolism (VTE) – Involving blood clots in the veins of the legs or the lungs; includes deep vein thrombosis (DVT) and pulmonary embolism (PE).

• Mechanical heart valves – Implantable devices, especially those with manmade surfaces, can cause blood clots to form.

• Thrombophilia – An increased tendency to form abnormal blood clots.

How can patients ensure they are getting a factory-new INR meter?

As the recognized leader in providing safe, accurate INR testing technology, Roche does not allow CoaguChek XS meters used for patient self-testing to be refurbished. 

Why is this important?

Re-use of improperly cleaned medical devices may be associated with multiple safety risks to patients, although insufficient data is available to definitely assess the risk of using refurbished medical devices.12 There’s no way to monitor or know the way meters previously used by patients for self-testing have been handled, cleaned, or stored.
