⚠️ T1D / CGM Safety Alert: FreeStyle Libre 3 & 3 Plus
Abbott has issued an urgent correction for some FreeStyle Libre 3 and Libre 3 Plus sensors after discovering they can give false LOW glucose readings.
Why this matters:
False lows can lead to:
– Eating extra carbs you may not need
– Skipping or delaying insulin
Over time, those decisions can be dangerous.
If you use Libre 3 / Libre 3 Plus:
👉 Go to www.FreeStyleCheck.com
👉 Tap “CONFIRM SENSOR SERIAL NUMBER”
👉 Enter your sensor serial number
👉 If it’s flagged, stop using it, dispose of it, and request a free replacement through that site
If your readings don’t match how you feel, confirm with a fingerstick / built-in meter.
🔎 Scope:
– This issue affects only a subset of Libre 3 / 3 Plus sensors tied to one production line
– Abbott reports that other Libre sensors, readers, and apps are not affected
