Trividia Health Updates True Metrix Blood Glucose Meter Instructions After FDA Alert

The U.S. Food and Drug Administration has issued an early alert regarding certain blood glucose monitors made by Trividia Health, citing 114 injuries and one reported death. The company recently corrected the instructions for use for four versions of its True Metrix systems, including True Metrix Air and True Metrix Self.

The update clarifies that patients should seek immediate medical attention if they experience symptoms of high blood glucose—such as fatigue, thirst or blurred vision—and receive an E-5 error code. The devices may display this code when blood glucose levels exceed 600 mg/dL or if a test strip error occurs.

The correction applies to devices distributed across the U.S., Mexico, the U.K., Australia and the Caribbean, including pharmacy-branded versions sold by CVS, Kroger and Walgreens. The devices do not need to be returned and may continue to be used.
