The FreeStyle Libre 3 reader is a standalone, small handheld device that displays real-time glucose readings.

The Food and Drug Administration (FDA) has cleared a standalone reader to be used with Abbott’s FreeStyle Libre® 3 integrated continuous glucose monitoring (iCGM) system.

The FreeStyle Libre 3 system consists of a small glucose sensor that is worn on the back of the upper arm. After scanning the sensor with the new handheld reader, the sensor sends glucose readings directly to the reader every minute. The device is powered by a rechargeable lithium-ion battery and should only be charged using the Abbott-provided USB cable and power adaptor.

“The FreeStyle 3 reader provides more choice to people living with diabetes to have access to lifesaving technology that is smaller and easier to use and comes without the high-cost burdens of other systems,” said Jared Watkin, senior vice president for Abbott’s diabetes care business.

Individuals who use the FreeStyle Libre 3 system will still have the option to use the current FreeStyle Libre 3 smartphone apps to check glucose levels. The Apps are compatible with iPhone and Android devices. However, if a user starts a new sensor with the reader, they will not be able to use the smartphone app to check glucose levels for the entire sensor wear period. A new sensor will need to be started in order to use the smartphone app to check glucose levels.
