The Guardian Connect System is a continuous glucose monitoring (CGM) system designed for individuals with diabetes mellitus aged 14 to 75 years. It monitors glucose levels in the interstitial fluid under the skin and provides real-time glucose values and trends via a mobile app. The system alerts users if glucose levels reach, fall below, rise above, or are predicted to surpass set values. It is intended to help users detect trends and track patterns in glucose concentrations, though therapy adjustments should be based on measurements from a home glucose monitor.
