FreeStyle Libre 3 and Libre 3 Plus sensors: some may read too low
- Affected
- Certain FreeStyle Libre 3 and FreeStyle Libre 3 Plus sensors made on one U.S. production line. Abbott checks them by the sensor's serial number.
- The problem
- Some sensors may show glucose readings that are falsely low. Treating a low that isn't real (like eating sugar or skipping insulin) can lead to high blood sugar.
- What to do
- Enter your sensor's serial number on Abbott's lookup. If it's affected, stop using it and ask Abbott for a free replacement. Throw away any sensors that have already expired.
