Alere INRatio Monitoring System

Suffered Complications From Alere INRatio Incorrect Test Results?

Our Alere INRatio Device Lawyers Can Fight For You & Win!

The Alere INRatio monitoring system and accompanying INRatio test strips have been connected to inaccurate International Normalized Ratio (INR) readings. This defective medical device has resulted in numerous injuries and serious ramifications for patients.


Simply put, the Alere INRatio Monitoring System is inaccurate. For certain medical conditions, this variance in INR can lead to serious medical complications. Deaths have been reported for people who mistakenly believed their international normalized ratio levels were safe, when in fact they were dangerously high. An Alere INRatio lawsuit involves allegations that the manufacturer knew of this potential problem, but failed to timely inform the U.S. government, healthcare providers and the public at large that Alere INRatio, INRatio2 PT/INR Monitor System, or INRatio Test Strips should not be used by patients undergoing specific therapies.

What Is the Alere INRatio Monitoring System?

Alere’s INRatio and INRatio 2PT/INR Monitor System and INRatio Test Strips are used to measure how quickly a patient’s blood clots, and specifically measures a patient’s Prothrombin Time when taking warfarin, a blood-thinning medicine. The International Normalized Ratio (INR) is used to compare the results of the patient’s Prothrombin Time.


Anticoagulant medicine (such as warfarin) is often prescribed to patients who have undergone replacement or mechanical heart valve surgery; have irregular heartbeats such as atrial fibrillation (arrhythmia of the heart); have had heart attacks; or are trying to prevent deep vein thrombosis (blood clots deep within the body) and pulmonary embolisms (blood clots in the lungs).

Injuries Caused by Inaccurate Readings Using Alere INRatio

When the Alere INRatio Monitoring System is used, patients may be at risk of serious injuries stemming from false readings. These INRatio injuries include:

  • Subdural Hematoma – Also referred to as subdural hemorrhage or bleeding in the brain, a subdural hematoma is often caused by a head injury significant enough to burst blood vessels. Blood-thinning drugs can increase the risk of subdural hematoma.
  • Hematoma Death – When a collection of blood fills outside the brain, the pressure can be life-threatening.
  • Mini Stroke – A “ministroke,” also called a “warning stroke” or “transient ischemic attack” (TIA), is a temporary interruption of blood flow to the part of the brain, spinal cord, or retina which has the same symptoms as a stroke but does not cause brain damage or permanent disability.
  • Stroke – A stroke is caused by an interruption of blood flow to the brain, resulting in brain damage and permanent disability. An Alere INRatio false reading could lead a patient to receive an improper dosage of blood-thinning medication, which could increase the risk of a blocked blood vessel.
  • Other Bleeding Events – Minor injuries can also be a serious problem with an Alere INRatio false reading. If a patient receives an improper dosage of blood-thinning medication, they can bleed to death.


The Alere INRatio Monitoring System is not accurate enough to replace laboratory testing.  Alere studies show that INR readings from Alere home INR monitoring can be between 3.1 to 12.2 units lower than laboratory results when tested within one hour to one day of each other. These inaccurate readings, according to the FDA’s safety alert, can cause severe medical complications, as patients and doctors are misled into believing that a patient’s international normalized ratio levels are in the therapeutic range when, in truth, the patient is at serious risk of suffering from bleeding events, including subdural hematoma (subdural hemorrhage) or stroke.

Alere INRatio Recall

If you or someone you know received a false PT/INR reading from an Alere INRatio Monitoring device and was injured after going through a bleeding event, you deserve monetary compensation. The list of dangers people face after receiving a false reading includes subdural hematoma (or subdural hemorrhage), brain bleeding, ministroke, stroke, or other bleeding events. In some cases, false readings can result in hematoma death.
