You can always consult the user manual or customer support if you're unsure about troubleshooting your device if you encounter specific problems. In some cases, simply turning your FreeStyle Libre 2 system reader off and on again can resolve the issue.

Troubleshooting Your FreeStyle Libre 2 System Reader

If you're experiencing issues with your FreeStyle Libre 2 System Reader, potential causes could include:

Inaccurate Readings

You may feel that the results the FreeStyle Libre 2 System Reader is giving are inaccurate, and feel that you may need to "reset" the reader. In most instances, you may simply need to unplug and plug it back in.

However, the reader plays no part in calculating glucose readings, so it is never responsible for inaccuracies,  and it is likely to be the FreeStyle Libre 2 sensor that is causing the disparity in readings when compared to a finger stick. This can be for a myriad of reasons, such as:

  • The sensor applicator is not placed in soft tissue.
  • Pressure against the actual sensor while sleeping, being dehydrated, or taking particular medications/vitamins/supplements.
  • You have a bad or old sensor.
  • Intense exercise.
  • Temperature and sensor storage conditions before use.
  • You have just eaten or taken insulin.

In fact, your glucose readings are likely not to be inaccurate at all. A CGM reading is different from the fingerstick comparison because it uses interstitial fluid to get the value rather than blood, and blood is quicker to react to changes in glucose than interstitial fluid. 

Software "Glitch"

This can cover a variety of issues. One example is, if a sensor falls off, a new sensor is inserted and scanned, but the reader says it is unable to start the new sensor. This can be a FreeStyle Libre 2 System Reader software issue or it may simply be a bad or old sensor.

Another example is when the sensor is going through warm up, it starts looping and repeating the warm up session but never actually starts. This too, could be a software problem or an issue with the sensor. There are different software glitches possible, but the resolution is always the same.

Instead of looking for a reset option, patients should speak to their healthcare professional, Libre Technical Support, or Aeroflow's CGM Specialist for assistance with troubleshooting their FreeStyle Libre 2 System.

As an example, an hour after eating, when blood sugar can be rising really quickly, there can be a wide difference between a fingerstick and CGM reading. To learn more about how to interpret the data from your CGM, you can schedule an appointment with an Aeroflow CGM Specialist here.

Clearing Out Old Data From Your FreeStyle Libre 2 System Reader

If a patient decides to give their reader to a friend or family member, they may feel they have to "reset" their reader in order to clear away all the readings that have been recorded and stored in it. 

Abbott states that the FreeStyle Libre 2 System is indicated for single-patient use only. Your CGM is not supposed to be given away or transferred to anybody; only to be used by who it was prescribed for.  Readings cannot be deleted from the device, and the reader cannot be reset. 

 If someone you know could benefit from a FreeStyle Libre 2 System, have them fill out our secure Eligibility Form to find out if they are eligible for their own CGM!

If issues persist with the FreeStyle Libre 2 System Reader, it is recommended the patient calls the Abbott customer support team for guidance, where you most likely would be provided with a replacement CGM if in-warranty.
