Improved Time in Therapeutic Range With Patient Self-Testing of Their INR Compared to Usual Care

Home testing monitor to test patients INR by placing a capillary drop of blood from the finger onto a test strip. The test strip is then inserted into the INRatio point-of-care self-testing coagulometer. After approximately 2 minutes of analysis, the INR value will be presented on the meter's display.

Usual care is defined as that care currently received by patients into whom mechanical heart valves are placed. Typically, these patients undergo frequent checks of their INR level until the therapeutic range is achieved. Then periodic INR levels are drawn at the discretion of the managing physician.
