Manufacturer Reason
for Recall
If blood glucose monitoring system users attempt to start a new sensor, when the old sensor wasn't used for the full 14-day wear time, then the reader may display "Incompatible Sensor" message. If users don't have the previous sensor, or FreeStyle Libre 2 app, or the sensor's full wear time hasn't ended, users may be unable to start a new sensor, which could result in no or delayed glucose results
FDA Determined
Cause 2
Software Design Change
Action On 7/12/23, correction notices were e-mailed or mailed to customers and distributors who were asked to do the following: If the "Incompatible Sensor" message is received when applying a new sensor and attempting it to start it with the Reader, follow these steps below. If previous Sensor retained: a) Wait 3 hours before scanning the previous sensor. While waiting, please use a blood glucose meter to check glucose. b) "Replace Sensor" should appear. c) Scan the new Sensor and "New Sensor Starting Up" screen should appear. If previous Sensor not retained: a) Users can use the free FreeStyle Libre 2 app to activate the new Sensor and get glucose data on the user's compatible smartphone. -The new Sensor that generated the "Incompatible Sensor" error message on the Reader can still be used with the app. -App can be download from the Apple App Store or Google Play Store. -To check smartphone compatibility, visit: https://www.freestyle.abbott/usen//products/freestyle-libre-app/compatibility.html b) Open the FreeStyle Libre 2 app c) Follow the instructions on the app to start the new Sensor. -Users can start the next Sensor with the Reader once a "Sensor Ended" is received. -Users can wait until the 14-day wear time for the previous Sensor has ended to activate the new Sensor with the Reader. The Reader Home Screen will indicate sensor wear days remaining. The Reader can be used as a blood glucose meter; this functionality isn't impacted by the Incompatible Sensor message. If not able to scan the previous Sensor and a compatible smartphone is not available, contact Customer Service at 1-855-632-8658 to receive further assistance. Additionally, contact Customer Service to report any adverse reactions or quality problems. Distributors should acknowledge receipt of the notice and provide the customer notice to all customers who were supplied Sensors since April 20, 2023.
