warfarin inr test meters is a portable, battery-operated meter, used to monitor patient response to warfarin. The meter has a screen that displays results, and an opening for meter-specific test strips. A test strip is inserted into the meter, and then a lancet is used to obtain blood which is applied to the test strip. The meter reads the test strip, measures how long it takes the blood clot, and provides the result based on a standardized calculation in the form of the International Normalized Ratio, or INR. The INR is used by patients and physicians to determine if warfarin dosing is appropriate.
Pt INR test meters and test strips are medical devices regulated by the U.S. Food and Drug Administration. The FDA wants to ensure patients and health care providers use these devices safely. Please read on for more information.
