MARD of ~8.5%
Dexcom G7 is a low-profile, all-in-one glucose sensor/transmitter and warms up faster than other CGMs on the market. This sensor lasts for 10 days and sends real-time glucose readings to a compatible smartphone app or directly on an Apple Watch. No finger pricks or scanning is needed. Optional low and high-blood sugar notifications are available for this system.
FDA-approved for wear on the back of the upper arm for ages 2 years and older or the upper buttocks for ages 2-17.
MARD of 8.2%
Components
Sensor
Sensor uses a thin, flexible filament beneath the skin to continuously measure glucose every 5 minutes. Simple, one-step applicator makes insertion fast and easy.
Sensor
Sensor uses a thin, flexible filament inserted just under the skin to measure glucose levels every 5-minutes. Push-button applicator allows sensor to be placed on the body in one step.
Receiver
Conveniently access glucose readings using a reader, smartphone, or directly on an Apple Watch. Phone app available for both iOS and Android devices.

Coverage will depend on insurance policies and Medtronic’s rollout plan
$$$$
No insurance coverage data. Provided by DME and/or Pharmacy.
Data Monitoring Options
Yes
Data streams directly to the pump; users and clinicians can view trends and logs via Medtronic’s platforms.
Yes
Automatically and continuously sends data to the user’s Dexcom Clarity web-based cloud which is accessible by clinicians.
Data View Options
Yes
Data view directly on your connected pump or smart device.
Yes
Users must download the Dexcom G7 and Dexcom Clarity apps to view and share data. Both apps provide multiple data views, sharing options, and access through the clinician portal using a code from the user's device. Caregivers can use the Dexcom Follow app to view data.
Duration and Storage
15 Days
Sensors last up to 15 days and need about 1 hour to warm up. They work between 50ºF – 113ºF and should be stored between 36ºF – 82ºF. They are usually shipped in 1–3 month supplies, which is about 2–6 sensors at a time.
10 Days
Sensors last 10 days. They are shipped 3 boxes at a time every 3 months – 9 sensors. Works at 50ºF – 108ºF

Patient Considerations
Active Lifestyle
Long wear & water resistant. Longer wear reduces change burden; sensor design aims for robustness with movement. Water-resistant up to 3 feet (1 m) for 30 minutes (same standard as FreeStyle Libre family).
Waterproof when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device.
Avoiding Highs and Lows
Continuous closed-loop insulin adjustment helps maintain tighter control.
Custom alerts can be set for highs, lows, and rapidly rising or falling glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
Comfort
Small & Discreet. Very small, discreet form factor, and minimal bulk.
Low profile and low maintenance sensor application.
Easy Insulin Dosing
MiniMed 780G closed-loop algorithm: adjusts basal and delivers automatic correction boluses using sensor data. Longer wear (15 days) means fewer interruptions in automated dosing. In manual mode, it still requires fingerstick confirmation before dosing from sensor values.
Real-time data and alerts make dose adjustment easier.
Easy to Use
Longer sensor life and shorter warm-up (~1 hour) help with convenience.
No scanning required. Readings are sent directly to the mobile app every 5 minutes.
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.
Factory-calibrated sensor. Finger sticks needed for backup only.
Privacy
Small & Customizable. Extremely small (about the size of two stacked pennies), designed to be less noticeable under clothing. Upper arm site only; discreet but still visible with sleeveless clothing. Alerts can be customized on the connected pump for quieter use.
Quiet Mode (Vibrate). All system alerts will vibrate when this setting is enabled. Urgent Low Soon and technical alerts will sound if not acknowledged.
