Abbott discontinued the FreeStyle Libre 14-Day System in January, 2021. Use the form below to see if you qualify for the FreeStyle Libre 2 or FreeStyle Libre 3 Systems.

Firstly, there are a lot more similarities than there are differences, the shape is identical. The main difference & the most significant improvement is the bluetooth connectivity which means that the Libre 2 now has the ability for optional alerts for high and low blood glucose readings.

The FreeStyle Libre system is clinically proven to be accurate, stable and consistent over 14 days with no fingerstick calibrations. The FreeStyle Libre system has a 9.2 % MARD with 99.9% of readings in Zones A and B of the Consensus Error Grid.

Use your smartphone* to scan the sensor as often as you like§. Stores 90 days of glucose data. Downloading data from the FreeStyle Libre 14 day system to the LibreView** software allows for even more in-depth analysis of your glucose data.

After 14 days of wear, the reader notifies the user that the Sensor has ended. The Sensor automatically stops collecting glucose data and should be removed 14 days after being started. Time to Sensor end is shown on the Home and Results screens.

The FreeStyle Libre 3 system has many improvements compared to the Freestyle Libre 2 and 14-day systems. The sensors are smaller, easier to attach, and they track glucose readings much better.

Your sensor automatically stops working after 14 days of wear and must be replaced. You should also replace your sensor if you notice any irritation or discomfort at the application site or if your phone or reader reports a problem with the sensor currently in use.

Abbott has recently identified that certain FreeStyle Libre® 2 sensors from lot KTP005061 may provide erroneously high glucose readings. For example, your sensor glucose reading may be high and out of your target range while your actual glucose levels may be below or within target range.

The gold standard for accuracy is a blood draw measurement and both finger sticks and CGMs have error margins (MARD) to that standard. Finger sticks tend to be in the range of 5-10% MARD, while the Libre has a MARD of about 9.7% over 14 days, and the Dexcom G6 has a MARD of 9% over 10 days.

You can scan as often as you want, but the reading will never change more frequently than every 60 seconds.

What happens if the FreeStyle Libre 2 sensor is worn beyond 14 days? The FreeStyle Libre 2 sensor automatically stops collecting glucose data and should be removed 14 days after being started.
