Abbott Laboratories has recalled a specific lot of its FreeStyle Libre 3 continuous glucose monitors after reports of inaccurate blood sugar readings that could lead to incorrect insulin dosing decisions. The recall affects approximately 45,000 sensors distributed to pharmacies and diabetes supply companies between January and March 2026.
The company says a manufacturing variance caused certain sensors in the affected lot to read blood glucose levels approximately 20 percent lower than actual values. For diabetic patients relying on the device to guide insulin dosing, falsely low readings could result in insufficient insulin administration and potentially dangerous hyperglycemic episodes.
Abbott is contacting healthcare providers and patients who received sensors from the recalled lot and is offering free replacement sensors. The FDA has classified this as a Class I recall due to the potential for serious health consequences. Patients using sensors from the affected lot are advised to verify readings with a traditional fingerstick blood glucose test and consult their healthcare provider about managing their diabetes during the replacement process.
