- Freestyle Libre 3 Plus
FreeStyle Libre 3 Plus is a continuous glucose monitoring (CGM) system designed to help people monitor glucose levels throughout the day and night. The system uses a small wearable sensor applied to the back of the upper arm, automatically sending real-time glucose readings directly to a compatible smartphone.
FreeStyle Libre 3 Plus can help users better understand how food, exercise, sleep, illness, and daily routines may affect glucose levels. Optional glucose alarms can also alert users when glucose levels are too high or too low.
The FreeStyle Libre 3 Plus sensor continuously measures glucose levels in the fluid just beneath the skin using a small wearable sensor.
Unlike earlier CGM systems that require manual scanning, FreeStyle Libre 3 Plus automatically sends glucose readings directly to a compatible smartphone app in real time, allowing users to:
- Monitor glucose trends continuously
- Review glucose history and patterns
- Receive optional glucose alarms
- Better understand daily glucose changes
Each sensor is designed to be worn continuously for up to 15 days before replacement.
FreeStyle Libre 3 Plus is commonly used by people living with Type 1 diabetes or Type 2 diabetes who need to regularly monitor glucose levels. It may also be suitable for some individuals with pre-diabetes or other clinician-advised glucose monitoring needs.
FreeStyle Libre 3 Plus is a glucose monitoring device and should be used in line with the manufacturer’s instructions. It does not replace professional medical advice, diagnosis, or emergency treatment.
You should speak to your GP, diabetes specialist, or healthcare professional if you have concerns about your glucose levels, diabetes management, or symptoms.
