Ways to Test


There's more than one way to test your warfarin patients.


How CoaguChek® total solutions benefit your patient and your practice.

When managing warfarin patients, it helps to think outside the lab. Studies have shown that self-testing offers many benefits compared to the laboratory testing, including the following:

  • Increased time in therapeutic range1
  • Reduced thromboembolic events1
  • Improved patient satisfaction2

CoaguChek systems offer a holistic solution that makes it easy to follow a systematic approach when managing warfarin therapy. Whether your patients self-test or receive point-of-care testing from healthcare professionals, you can improve quality of care, patient satisfaction and workflow efficiency.

Patient Self-Testing (PST)
Self-testing benefits patients and practices

With self-testing, managing your patient's warfarin therapy has never been more efficient or effective. Together, the services and products offered by CoaguChek® Patient Services will help ease the workload for doctors and the clinic staff while empowering your patients to self-test their INR from home or on the go. 

Accurate INR results are transmitted wirelessly to CoaguChek Link so you can make immediate, data-based adjustments of warfarin therapy.3


There are a number of advantages of INR self-testing for your patients, including the following:
  • Self-testing provides patients with the tools and flexibility to be more engaged in their therapy and this can result in better compliance and improved time in therapeutic range (TTR).2
  • Self-testing helps eligible patients participate in their treatment, leading to greater patient satisfaction and a higher quality of life.1
  • Patients make fewer trips to the hospital lab for testing, enabling them to enjoy a greater quality of life.
  • Venous punctures are not necessary; only a drop of blood from the fingertip is required to run a test. 

For your patients, INR self-testing at home can be a convenient alternative to lab testing.  CoaguChek Patient Services provides warfarin monitoring tools to you and your patients to help optimize your workflow into three simple steps:

The benefits of point-of-care INR testing

Point-of-care INR testing is an efficient and effective way to manage warfarin patients. In a study evaluating PT/INR testing methods, patients who participated in point-of-care INR testing experienced 91 percent fewer complications than patients who received laboratory testing for INR.1 What’s more, their in-range INR results improved by 97 percent.1
