The U.S. Food and Drug Administration (FDA) has approved the Dexcom G5 Mobile Continuous Glucose Monitoring (CGM) System. With wireless Bluetooth technology built into the device transmitter, the G5 Mobile CGM System is the first and only fully mobile CGM system approved by the FDA for both adults and children as young as 2 years of age that sends glucose data directly to a smartphone, freeing users from the need to carry a separate receiver.
