Warfarin INR Test Meters

Warfarin must be monitored to ensure it is working effectively and being used safely. Achieving the correct warfarin dosage can be difficult but is extremely important. If the dose of warfarin is too low, the patient is at risk of developing harmful blood clots. If the dose of warfarin is too high, the patient may be at risk of serious bleeding. It can be monitored by drawing blood from a vein and sending the blood to an accredited laboratory to test, or it can be monitored by testing blood from a fingerstick with an pt INR test meter outside of a laboratory. INR test meters may be prescribed

  1. Warfarin INR Test Meters warfarininr 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. 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.

  2. What is Warfarin?

  3. Monitoring Warfarin Warfarin must be monitored to ensure it is working effectively and being used safely. Achieving the correct warfarin dosage can be difficult but is extremely important. If the dose of warfarin is too low, the patient is at risk of developing harmful blood clots. If the dose of warfarin is too high, the patient may be at risk of serious bleeding. It can be monitored by drawing blood from a vein and sending the blood to an accredited laboratory to test, or it can be monitored by testing blood from a fingerstick with an pt INR test meteroutside of a laboratory. INR test meters may be prescribed to patients for use in the home, and they may also be used by health care providers at the point of care, such as a health care setting.

  4. How often an INR test meter is used to monitor warfarin, and the results a patient should expect, will be based on recommendations from the patient’s health care provider. Anticoagulation Machine An INR target range is set by a health care provider. Heart Valve Disease It is typically between 2.0 and 3.0 for basic blood-thinning needs, though the range may vary based on a patient’s specific conditions. An INR above the patient-specific target range may increase the risk of bleeding, while an INR below the target range may increase the risk of developing a blood clot.Patients should work with their health care provider to develop a plan for achieving and maintaining a target INR; recognize when there is a problem; and know when to contact their health care provider. The information and resources on this website are intended to provide useful information for patients and caregivers who are using INR test meters in the home and for health care providers using INR test meters in a clinical setting.
