Pediatric continuous glucose monitoring system FreeStyle Libre 3

CGMwith subcutaneous sensorpatch

Overview
The FreeStyle Libre 3 system provides real-time, minute-by-minute glucose readings for children so caregivers can monitor glucose without frequent fingersticks. The system is designed to be small, discreet and comfortable to wear on the back of the arm and works with companion apps to share readings with caregivers and healthcare providers.

Key benefits

• Accurate, minute-to-minute glucose readings to help act faster to avoid hypoglycemia.
• Optional alarms to help prepare children for future self-management.
• Seamless sharing of glucose readings with caregivers and healthcare providers when sharing is enabled.
• Works with the Libre app for automatic updates on a smartphone every minute and with LibreLinkUp for caregiver sharing.

Apps and connectivity

The Libre app provides automatic minute-by-minute updates and an option to silence select alarms for up to 6 hours to reduce interruptions. Sharing requires internet connectivity for automatic uploads and may depend on device compatibility.
