Getting-started checklist
Are you ready to take the first step toward simplifying your INR monitoring?

Here’s a checklist for starting your journey of self-testing using a CoaguChek® Vantues or CoaguChek® XS meter. It’s easier than you might think – and we’re here to help, every step of the way. 

 

Step 1 - Your doctor sends in your patient information.

Your doctor submits the Physician Order Form (your prescription) and Patient Authorization Form online to CoaguChek Patient Services.

CoaguChek Patient Services schedules an in-person training by a certified healthcare professional or by your doctor's office staff. During training, you'll learn the importance of testing as prescribed and how to:
•  Use the CoaguChek Vantus or CoaguChek XS meter

•  Order supplies
 

Step 4 - CoaguChek Patient Services manages results and compliance.

We'll collect and communicate all results and notify your doctor of out-of-range results. We also have a convenient program that helps keep you on your perscribed testing schedule and reminds you if you miss reporting a result.

How to perform a self-test
Testing your INR with a CoaguChek Vantus or CoaguChek XS meter is convenient and easy.
Follow these simple steps to perform a self-test anywhere and at any time.*
 

1. Wash your hands in warm, soapy water. Be sure to rinse and dry thoroughly before testing.

2. Place the meter on a secure, level surface, such as a countertop or table, or hold it horizontally in your hand. 

3. Remove a CoaguChek XS PT Test strip from its container. Close the container immediately with the stopper.

4. Slide the CoaguChek PT Test strip into the meter in the direction of the arrows. Slide the test strip in as far as it will go.

5. Wait for your meter to warm up. An hourglass icon will appear on the display. Once you hear a beep, the meter is ready. You will then have 180 seconds to apply blood to the clear window on the strip. 

6. Use a fresh lancet and lancing device to draw a drop of blood from the side of your fingertip. It’s important to apply the blood drop to the strip within 15 seconds of drawing it. 

 

Tips to get a good blood sample:

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

     •  Massage the finger to be pricked. 

     •  Warm your hand by holding it under your arm or using a hand warmer.

7. Apply the blood drop to the test strip until the meter beeps. The meter will beep again, and the results will appear – this is your INR value.

8. Report your results wirelessly to CoaguChek Link with the Bluetooth -enabled CoaguChek Vantus system and CoaguChek Patient Services.1 Alternatively, you can enter results online using a computer, or call them in over the phone.

*The CoaguChek XS system may be used up to a maximum altitude of 14,000 feet.  The CoaguChek Vantus system may be used up to a maximum 13,120 feet

Diet and medication
Some foods and medications can lessen the effectiveness of your warfarin treatment.

To ensure your INR results are where they should be, it’s important to maintain a consistent, balanced, healthy diet. Here’s what you need to know before you start self-testing with a CoaguChek meter.

 

1. Watch your vitamin K intake.

Produced by your body as part of the clotting process, vitamin K is also found in many green, leafy foods, such as kale, lettuce, spinach and broccoli. High amounts of vitamin K can reverse warfarin’s blood-thinning effect.1 Does this mean you should cut back on foods high in vitamin K? No, but a consistent diet is important, as your doctor will base your recommended warfarin dose on your regular diet. Visit our newsletter library for more insights on the role of vitamin K in your diet.  

 

2. Avoid alcohol.

Because it immediately decreases your blood’s ability to clot, alcohol should be avoided when taking warfarin. Even if your INR levels remain within the target range, the risk of major bleeding is increased.2 What’s more, after episodes of excessive drinking, clotting can increase, putting you at greater risk of heart attack or stroke.3

 

3. Tell your doctor about other medications and supplements.

Because warfarin can interact with many drugs and supplements,4, 5, 6 tell your healthcare provider about everything you take, including these over-the-counter medications and supplements:
•  Acetaminophen (e.g., Tylenol)
•  Aspirin, including ointments/creams
•  Ibuprofen (e.g., Advil)
•  Naproxen (e.g., Aleve)
•  Non-steroidal anti-inflammatory drugs (NSAIDs)
•  Heartburn or acid reflux medicines (e.g., Nexium, Zantac)
•  Cold/allergy medicines
•  Antibiotics
•  Herbal supplements (e.g., Ginkgo biloba, ginseng, St. John’s wort)
•  Birth control pills
•  Vitamin supplements with vitamin K
