Ask Your Doctor About the Benefits of INR Self-Testing, Then Call 1-800-780-0675 to Get Started
To measure how long it takes your blood to clot, your doctor will order a test for your INR, or international normalized ratio, to measure the amount of warfarin (a blood thinner) in your blood.
Testing at home or anywhere that is convenient is easy with Remote INR. We provide you with the same testing technology that doctors and nurses use in their offices. A healthcare professional trained to provide self-testing training can teach you how to use the device. Here’s an overview of the process:
Test yourself anywhere, at the frequency prescribed by your doctor.
Once your doctor or healthcare provider receives your results, they will contact you if any changes are or are not necessary for your warfarin dose.
Collect just one drop of blood.
It helps you stay on target.
(A study has shown that self-testing may result in increased time in the therapeutic range.1)
Test anywhere, anytime.*
Use your small, portable meter.
You don’t have to worry about travelling or waiting.
Get results in one minute.

*The CoaguChek XS system may be used up to a maximum of 14,000 feet. The CoaguChek Vantus system may be used up to a maximum of 13,120 feet.
All three ways provide accurate results. However, many warfarin patients choose self-testing for the freedom and convenience it provides.

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.
Anticoagulants (commonly called “blood thinners”) are medication such as warfarin. These drugs help thin the blood of patients with conditions such as atrial fibrillation, thrombophilia and other diseases that increase the risk of forming blood clots.
Warfarin is a widely used anticoagulant for appropriate patients, given in tablet form, that must be regularly monitored. It may be prescribed to patients for weeks, months, or even years.
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.1 Drugs like warfarin are anticoagulation medications that slow down the clotting process to help keep you in a safe range.
If you are taking warfarin, then INR testing is a required part of your ongoing therapy. INR stands for “international normalized ratio.” It is a standardized reporting system established by the World Health Organization (WHO). It is used as the measure of a patient’s level of anticoagulation when being treated with warfarin. INR is monitored to ensure patients who are taking warfarin are in the therapeutic range (the right amount for their condition).
Your INR results let your doctor know whether you’re taking the right amount of warfarin to keep you in range and on track. Testing is a continual commitment between you and your doctor. However, once you know your options, you’ll see how it can become a simple part of your routine.
Alcohol can increase the effect of your medication and further slow your clotting rate, causing your INR to be too high. You may want to avoid it while on anticoagulation medication. Talk to your doctor about what’s appropriate for you.
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.
Any condition that results in an increased risk for blood clots and is treated with an anticoagulant, such as warfarin (sometimes known as Coumadin® or other brand names), will require regular testing. These include:2
The goal of monitoring your INR is to remain in the target range recommended by your doctor. In general, an INR target therapeutic range of 2.0 to 3.0 is appropriate3–8, however this is dependent on the indication for which you are receiving a VKA and other variables.5,6,9. Please consult and follow the instructions of your doctor regarding the appropriate range for you.
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 INR is too low, you may still be at risk of excessive clotting.8 Please consult your doctor if your INR value is outside of your recommended target range.
Many things can alter your INR, including stress, missing a dose of your vitamin K antagonist therapy, taking herbal supplements and other medications, and consuming certain foods and beverages, such as kale and cranberry juice. Talk to your doctor about what’s appropriate for you.
Test frequency should be determined by your doctor.
A vitamin K antagonist (VKA) works by blocking the body’s ability to use vitamin K, a necessary component in the formation of blood clots. When you’re taking this type of medication, it’s important to keep the amount of vitamin K in your diet consistent, or it may impact the effectiveness of your VKA doses.10
Green vegetables such as spinach, kale and broccoli are high in vitamin K,11 as are the following foods:
Remote INR is designed to help you enjoy the freedom of INR self-testing.
When you receive your new CoaguCheck Vantus, the Remote INR team will teach you how to use it. Representatives can answer any questions you might have about the process of test your INR. After your meeting, they’ll remain available to provide ongoing support.
Starting with the Remote INR portal is easy. Just call 1-800-780-0675 today. Your doctor will then be contacted for the prescription information needed to start your enrollment process.
