The FreeStyle Libre Flash Glucose Monitoring System is indicated for measuring interstitial fluid glucose levels in people (age 4 and older) with insulin-requiring diabetes mellitus. The indication for children (age 4 - 17) is limited to those who are supervised by a caregiver who is at least 18 years of age.
FreeStyle Libre Reader
Note: The FreeStyle Libre reader is not compatible with the FreeStyle Libre 2 sensor.
FreeStyle Libre 2 sensors can only be used with the FreeStyle LibreLink app on a compatible smartphone. To ensure you have a compatible phone, check our compatibility guide.
The FreeStyle Libre reader displays the glucose data collected by the sensor. An easy 1 second scan shows the current glucose reading, the latest 8 hours of glucose data and a trend arrow showing if glucose levels are going up, down or changing slowly.
