CoaguChek® INRange

For confident control of Vitamin K antagonist (VKA) therapy
CoaguChek® INRange is the connected self-testing meter that enables your patients to self-test their International Normalized Ratio (INR) whenever, wherever.*
The CoaguChek INRange system determines prothrombin time (PT) in fresh capillary blood, a coagulation test to monitor VKA therapy.
CoaguChek technology and quality have been recognized to facilitate VKA patient self-testing in a safe, accurate, and reliable manner.1
