The most accurate CGM system1
With an 8.2% overall MARD for adults and an 8.1% MARD for children,2 Dexcom G7 is the most accurate CGM system available.1
MARD (mean absolute relative difference) is a statistical measure of CGM accuracy; the lower the number the better. With unmatched accuracy,1 you can have confidence in the numbers that you see, so you can make smarter decisions with food and activity in the moment.
Your glucose numbers without fingersticks†
A small wearable sends real-time glucose readings to the Dexcom G7 app or receiver every 5 minutes, no fingersticks† or scanning required. You’ll see where you are, where you’re headed, and where you’ve been, making it easier to make better diabetes management decisions.
†Fingersticks required for diabetes treatment decisions if symptoms or expectations do not match readings.
Customizable alerts that work for you.
The Dexcom G7 app gives you the flexibility to customize alert sounds and settings to best fit your lifestyle and needs.
Smart device sold separately.*
Urgent low soon alert
Provides a 20-minute advance warning of when you’ll reach 55 mg/dL so that you can act quickly and avoid a potential hypoglycemic event.
Establish alert levels so you can get a Low Alert or High Alert when readings are below or above target range. You can also choose the sound for each alert.
Delay 1st alert
Enables you to delay your first High alert until your sensor reading is high for a while. You choose how long.
When this setting is enabled all your G7 alerts will vibrate. Your Urgent Low Glucose and Technical Alerts will still escalate to sound if not acknowledged.
Track your progress. Reach your goals.
You can track your progress by viewing the integrated Dexcom Clarity card, which provides insights into your glucose patterns directly in the Dexcom G7 app.‡,§ The more you know, the easier it is to stay in range, which can lower your A1C.
