Abbott FreeStyle Libre 3 Sensors: Erroneous High Glucose Readings Risk Hypoglycemia
Abbott recalls FreeStyle Libre 3 Sensors with serial numbers starting with T60001948 and 0FP5Z... that may show falsely high glucose levels, leading to incorrect insulin doses and missed hypoglycemia detection. Users should stop using affected sensors immediately.
Stop using this now
Users of the FreeStyle Libre 3 sensors reported situations where they were receiving erroneously high glucose results. The inaccurate higher glucose values may lead to users calculating higher insulin bolus correctional doses based on inaccurate CGM glucose data. The inaccurate higher glucose values may also contribute to missed or delayed recognition of hypoglycemia, when the sensor incorrectly reports normal or even high glucose values when the actual glucose is trending low or is low. If the hypoglycemia missed by the device occurs acutely, a user may not be able to confirm the actual glucose with a self-monitored blood glucose (BG) and/or administer prompt intervention to raise glucose levels. The over-delivery of insulin and/or the missed or delayed detection of impending or overt hypoglycemia in the worst-case scenario may lead to severe hypoglycemia/hypoglycemic crisis with significant adverse health consequences. Such consequences include central nervous system dysfunction, loss of consciousness, seizure activity and may lead to coma, permanent neurological damage, and death.

What happened, in plain English
Abbott is recalling FreeStyle Libre 3 glucose sensors that may show falsely high glucose readings. This can cause users to take too much insulin or miss low blood sugar events, potentially leading to severe hypoglycemia, loss of consciousness, or even death if not addressed.

“Abbott FreeStyle Libre 3 Sensors: Erroneous High Glucose Readings Risk Hypoglycemia.” GovInfoNow, updated August 19, 2026. https://govinfonow.com/recall/54554-abbott-freestyle-libre-3-sensors-erroneous-high-glucose-readings-risk. Based on FDA recall #Z-2692-2024 (https://api.fda.gov/device/enforcement.json?search=recall_number:%22Z-2692-2024%22&limit=1).
Why it’s dangerous
The sensors may report glucose levels higher than actual, causing users to calculate higher insulin doses than needed. This can lead to missed or delayed recognition of low blood sugar (hypoglycemia), which may result in severe health consequences like loss of consciousness, seizures, coma, permanent neurological damage, or death.
Who’s affected
People using Abbott FreeStyle Libre 3 glucose sensors with specific serial numbers (T60001948 and 0FP5Z...) are affected. Those with diabetes who rely on continuous glucose monitoring are most at risk.
How to tell if you have this one
Check your FreeStyle Libre 3 sensor's serial number. Affected units have serial numbers starting with T60001948 or 0FP5Z... (the full list is provided in the recall notice).
