Abbott flags risk of inaccurate low glucose readings in some Libre 3 sensors
Global healthcare company, Abbott, initiated a medical device correction for certain FreeStyle Libre 3 and Libre 3 Plus sensors in the U.S. after internal testing revealed some may report falsely low glucose readings. The issue affects about 3 million sensors, roughly half of which are believed expired or used. Globally, Abbott has received 736 reports of severe adverse events (57 in the U.S.) and seven deaths, potentially linked to this issue. None of the deaths occurred in the U.S. Abbott has resolved the manufacturing problem and is offering free replacements; consumers can check affected sensors at www.FreeStyleCheck.com. No other Libre products, readers, or apps are impacted.
