Dexcom G7
Description
Looking for the most cutting-edge CGM on the market? Dexcom is a leader in CGM manufacturing and their latest continuous glucose monitoring system–the Dexcom G7, is just that. With a MARD (Mean Absolute Relative Difference) of 8.2%, it is currently the most accurate CGM available.
Dexcom G7 tracks glucose levels in real-time and sends the data to your receiver or smartphone via the app–no finger sticks required.* With glucose readings every 5 minutes and 180 days of data storage, you’re always in the know. Choose from a variety of customizable alerts, including delaying first alerts, “urgent low soon” alerts, and quiet mode with the Dexcom G7 app.
Building off the success of the G6, the G7 offers some major improvements to its predecessor. It has a much shorter warm-up time of only 30 minutes. Other brands require an hour at minimum. The G7 also has a small all-in-one sensor/transmitter. Check out our guide on the Dexcom G6 vs G7 for more details.
The Dexcom G7 CGM system comes with a handheld receiver and a 90-day supply of sensors to get you started. Each sensor can be worn for up to 10 days, even in the shower. Already have the G7 receiver and are looking to replenish sensors? You can order Dexcom G7 sensors from US MED here.
Dexcom G7 may be covered by your insurance or Medicare plan. To see if you qualify, start your order or call us at 877-840-8218.
