INR At Home: Where Accuracy Meets Comfort

Abstract:
Warfarin safety and efficacy is assessed using weekly to monthly international normalized ratio (INR) checks. Many disease states necessitate that the INR remains within a specified therapeutic range to ensure warfarin is being dosed appropriately. This requires patients to go to a clinic or a lab to have their INR checked to ensure it is within range. The integration of INR self-testing devices provides a validated way for patients to measure their INR from home, providing patient autonomy and comfort. The purpose of this manuscript is to review INR self-testing, how it works, its effectiveness, and its implications for patient care.
