Abbott Issues Warning for Certain FreeStyle Libre 3 Sensors
Some FreeStyle Libre 3 continuous glucose monitoring sensors could display false high readings and should be immediately discontinued, urged the manufacturer. Affected sensors will be replaced at no cost.
Abbott, maker of the FreeStyle Libre 3 continuous glucose monitor device, announced today that a small number of sensors could display false high glucose readings. This might lead people to see an incorrect high blood sugar reading and take insulin unnecessarily – a potentially dangerous situation.
The Libre 3 system includes an app, reader, and sensor. The reader and app are not affected, only the sensors. The company is urging people to immediately discontinue using sensors from any of these three lots:
- T60001948
- T60001966
- T60001969
Abbott is offering replacements at no cost for any of the affected units. The sensor lot number is printed on the bottom of the sensor kit’s carton. If you no longer have the carton, you can determine the lot by serial number, which is also found on the bottom of the packaging labeled as “SN.”
If you want to check the lot number of a sensor you are wearing, you can find it displayed in the FreeStyle Libre 3 app or reader. You can also search for the lot number here: www.FreeStyleConfirm.com.
The company said all sensors with other lot numbers can continue to be used. This voluntary medical device correction does not affect any other Libre product, including the Libre 14 day, Libre 2, or Libre 2 Plus, or products outside the U.S.
To request a replacement, confirm your sensor serial number here. If your sensor is impacted, you will be instructed to enter your contact information so a replacement product can be sent to you free of charge.
If you have symptoms that do not match the sensor glucose reading or suspect your reading may be inaccurate, double-check by conducting a fingerstick test using any blood glucose meter. The built-in blood glucose meter in the FreeStyle Libre 3 reader can also be used to check your glucose.
