Coagulation self-monitoring with CoaguChek®

Coagulation self-testing means less time at the clinic


Self-testing with CoaguChek® gives you the freedom to test your INR levels yourself, anytime you like. Self-testing at home can give you better control of your medication than testing at a laboratory or doctor’s office, with more time in your therapeutic range. Your doctor will receive and monitor your results, so when your dose does need changing, you can find out sooner.


What is time in therapeutic range (TTR) and why is it important

Time in therapeutic range

The TTR is the percentage of time a patient spends with an INR level that is deemed ideal for their condition.

The therapeutic range is quite narrow, and INR can be affected by many factors, including diet and other medical conditions.

Time in therapeutic range

By monitoring INR, VKA dosage can be adjusted as required to maintain a high TTR.

However, infrequent testing can mean that deviations of INR outside of the TR may not be determined for a period of time.

More frequent monitoring of INR levels together with lifestyle changes can help maximize time you spend within therapeutic range.1

Every model of care is trying to achieve the highest TTR possible.

A high TTR is directly linked to a reduced rate of adverse effects2-4
