The FreeStyle Libre 2 system is the latest diabetes monitor system from Abbott. It offers a user experience similar to that of its predecessor, newly enhanced with a number of noteworthy features.


Glucose Monitoring For (Almost) All Ages
Unlike the original FreeStyle Libre system, the FreeStyle Libre 2 can be used by both adults and children as young as 4 years old.

Get Connected
The FreeStyle Libre 2 has been designated as an iCGM by the FDA - that means it’s capable of digital communication with other devices.

Alarming Feedback
With the FreeStyle Libre 2, you can choose to receive real-time glucose alarms that will let you know when your levels are too low or high.

Accurate Results - Fast
This system will give you the quick, reliable glucose readings FreeStyle Libre is known for.



The FreeStyle Libre 2 system has been designed for use with its own app for smart devices. As of April 2021, however, the FreeStyle Libre 2 app was still under FDA review. In the meantime, the system can be used with a dedicated reader.

How FreeStyle Libre Systems Work

Whether you choose the FreeStyle Libre 14 day system or the FreeStyle Libre 2, the process of getting started with your new CGM is simple. First, you’ll choose a site to wear the sensor and clean the skin there. Then you’ll open your sensor pack, place it on a hard surface, and press down on it firmly with the included applicator. Finally, put the sensor applicator on your chosen site and press down firmly until the sensor is in place.

Once your sensor is in place, you’ll be able to scan it regularly with your reader. FreeStyle sensors are designed to stay in place for up to 14 days, so you won’t have to worry about replacing it for quite some time!
