Glucose Monitoring

Abbott Freestyle Libre

By in Glucose Monitoring

Abbot’s Freestyle Libre uses flash glucose monitoring, and the data are available by “waving” the receiver or a compatible iPhone (series 7 or later) within 1.5 inches of the sensor. No finger stick blood glucose calibration is required for the FreeStyle Libre to calculate insulin doses, but the device may require calibration under rare circumstances. Libre devices are approved in ages 4 years and older, and can be worn for 14 days. There are currently 2 versions of the Libre available:

  • Freestyle Libre 2 with Libre 2 app or reader
  • Freestyle Libre 3 with Libre 3 app
  • Freestyle Libre 14 day with Libre Link app

Both are disposable all in one sensors that are easy to insert. The Libre devices are comparatively inexpensive and in some cases, have the same out of pocket cost as a blood glucose meter and test strips.

Both systems have a mandatory urgent low glucose alarm that sounds at 55 mg/dL. They also have high and low glucose alarms that can be adjusted by the person using the device. There is also a signal loss alarm.

Both systems can be connected to the LibreLink site to review data and share it with your care team.
