FreeStyle Libre 3 Plus Sensor is a continuous glucose monitoring (CGM) sensor designed for people living with diabetes who want real-time insight into their glucose levels with minimal disruption to daily life. It offers extended wear, reliable performance and seamless connectivity, helping users manage their glucose trends more confidently while reducing the need for routine finger-prick tests. With a small, discreet profile, optional glucose alarms and integration with compatible insulin delivery systems, it suits adults, pregnant users and children from 2 years of age who are looking for flexible, data-driven diabetes management. Clinical research on the 15-day factory-calibrated sensor used in Libre 3 Plus has shown accurate glucose readings across the wear period, supporting informed therapeutic decisions.

Key Features

• Extended 15-day wear: Provides up to 15 days of continuous glucose monitoring, meaning fewer sensor changes and a smoother routine over each month of use.
• Real-time readings to your phone: Streams glucose data automatically, typically every minute, to a compatible smartphone app or reader so you can see current values and trend arrows at a glance.
• Insulin pump and AID compatibility: Works with select insulin pumps and automated insulin delivery systems, enabling integrated diabetes management with coordinated glucose data and insulin delivery.
• Small, discreet and comfortable: Uses one of the world’s smallest CGM sensor designs, worn on the back of the upper arm with no over-bandage required, helping it sit low under clothing while remaining secure.
• Advanced accuracy and wide suitability: Factory-calibrated sensor technology has demonstrated accurate readings over the full 15-day wear period, and the device is indicated for users aged 2 years and above, including pregnant individuals, supporting a broad range of clinical needs.

Is the FreeStyle Libre 3 Plus Sensor more accurate than previous versions?

Both Libre 3 and Libre 3 Plus sensors meet high regulatory standards for CGM accuracy, with Libre 3 Plus evaluated for accuracy across its full 15-day wear time. The improved sensor design also reduces interference from substances such as vitamin C, helping maintain stable performance across typical daily conditions.

How does FreeStyle Libre 3 Plus differ from the standard FreeStyle Libre 3 Sensor?

Libre 3 Plus extends sensor wear from up to 14 days to up to 15 days and adds compatibility with certain insulin pumps and automated insulin delivery systems. It also widens the approved age range to children from 2 years old, while retaining the same small form factor and real-time streaming of glucose data.

Who is the FreeStyle Libre 3 Plus Sensor suitable for?

The sensor is suitable for adults and children aged 2 years and older who require continuous glucose monitoring, including those who are pregnant. It can be particularly appealing for people using or considering insulin pumps, as well as those who value real-time data, optional alerts and reduced finger-prick testing.

Which devices and apps can I use with the FreeStyle Libre 3 Plus Sensor?

Libre 3 Plus works with compatible versions of the FreeStyle Libre 3 app and Libre reader, and data can be shared with healthcare teams via platforms such as LibreView and with carers through LibreLinkUp. Device and operating system compatibility varies, so users should check the current compatibility information before relying on a specific smartphone or operating system.

How does the extended wear time help with day-to-day diabetes management?

The 15-day wear duration means you typically need only about six sensors over 90 days, which can reduce interruptions, packaging waste and planning around change days. In combination with continuous, minute-by-minute readings and optional alarms, this extended wear makes it easier to follow glucose trends, adjust therapy with your clinical team and maintain an active lifestyle with fewer disruptions.
