Alere® INRatio / INRatio2 Monitor & Test Strips

Back on December 8, 2014, Alere sent a letter to it’s U.S. Consumers notifying them of important information in regards to their Alere INRatio (or INRation2) test monitor and test strips. The letter stated the FDA recall has been issued for the device.

In the letter, Alere listed several medical conditions which could affect the accuracy of INR readings given to consumers. These conditions include:

  • Anemia (low hemoglobin or red blood cell count)Alere-INRatio-monitor-system-class-action-lawsuit
  • Unusual or unexplained bleeding and/or bruising
  • Conditions which produce elevated levels of fibrinogen such as:
    • Acute inflammatory conditions like pneumonia or influenza,
    • Chronic inflammatory conditions like rheumatoid arthritisCrohn’s disease, ulcerative colitis, hepatitis and other infectious liver diseases or inflammatory kidney diseases,
    • Severe infections such as sepsis, or
    • Advanced stages of cancer or end stage renal disease requiring hemodialysis

    Alere issued a recall for its INRatio PT/INR test strip and monitor system because it may produce inaccurate (usually too low) INR readings.  By using this medical device, consumers may be at risk of severe injuries such as bleeding events, subdural hematomas, strokes or mini-strokes and even death.

    The U.S. Food and Drug Administration (FDA) reports Alere admitted to receiving almost 19,000 complaints of malfunction by INRatio users.  The FDA has classified this recall as a Class I recall, the most serious category of recall.   Class I recalls involve situations where the use of a medical device will likely cause a serious injury or death to a consumer.
