Patients on vitamin K antagonist therapy (VKAs), such as warfarin, have a narrow therapeutic window and require regular international normalised ration (INR) monitoring to maintain optimal coagulation. The LumiraDx INR Test is a point of care test which measures quantitative prothrombin time (PT), reported as INR. Results are available from fresh capillary whole blood in 60-90* seconds.
Point of care INR testing provides several benefits over standard INR monitoring, including:
