FreeStyle Libre 14-Day Sensor (4-Pack)

The FreeStyle Libre System is the only CGM able to maintain accuracy over 14 days without needing fingerstick calibration or sensor coding and it gives your first reading just one hour after sensor application.

The sensor for the FreeStyle Libre System is small, discreet and water resistant. The sensor is worn on the back of the upper arm. The thin design of the FreeStyle libre sensor has a thickness about the size of two stacked quarters. The sensor can easily be scanned through clothing. After the 1 hour start-up period, the sensor can be worn for up to 14 days. The FreeStyle libre sensor automatically measures glucose every minute. No finger-stick calibrations required.
