FreeStyle Libre 3 System | Continuous Glucose Monitoring

It’s a continuous glucose monitoring (CGM) system featuring a super‑small, factory‑calibrated sensor worn on the back of the upper arm for up to 14 days (with an extended 15-day version available), paired with either a smartphone app or a dedicated reader for real-time glucose tracking.

The system includes optional glucose alarms (low, high, and signal loss) and automatically transmits minute-by-minute readings via Bluetooth—no fingersticks or manual scans needed.
