Dexcom G7 Sensor Kit - Box of 1
Description
The Dexcom G7 CGM System is Dexcom’s most advanced continuous glucose monitoring system yet—now available in two wear options:
Dexcom G7 (10-day wear) – FDA-cleared for ages 2 and older
Dexcom G7 15 Day (15.5-day wear including 12-hour grace period) – FDA-cleared for adults 18+
Both sensors deliver real-time glucose readings every 5 minutes, require no fingersticks*, and are 60% smaller than previous models†. They warm up faster than any other CGM sensor†† and work with the Dexcom G7 app or receiver for easy monitoring.
Dexcom G7 Sensor Kits may be covered by your insurance or Medicare. To see if you qualify, fill out the form or call us at 877-840-8218.

How to Apply the Dexcom G7 Sensor
Step One: Choose a Sensor Site The area where you’ll wear your Dexcom G7 sensor can vary based on your age. If you are at least seven years old, you’ll wear this sensor on your abdomen or the back of your upper arms. Dexcom G7 users between 24 months and six years of age can wear sensors on either of those sites or on the upper buttocks.
Step Two: Clean and Dry the Site No matter what site you choose for your Dexcom G7 sensor, it needs to be clean. Wash your hands before rubbing the sensor site with an alcohol wipe, and wait until the area is dry before proceeding.
Step Three: Insert the Sensor When you’re ready to apply the sensor, unscrew the applicator cap. When that’s done, relax your muscles near the sensor site and press and hold the applicator against your skin before pushing the button.
Step Four: Remove the Applicator Once the sensor is applied, remove your applicator and screw its cap back on. Be careful not to throw away the applicator - you’ll need access to its pairing code.
Step Five: Keep Your Sensor in Place Secure your Dexcom G7 sensor by firmly rubbing three times around the patch and pressing down on the sensor for 10 seconds. If your sensor needs to be secured further, use the overpatch included in your sensor kit.
For a complete breakdown of the Dexcom G7 sensor application process, refer to Dexcom’s official sensor insertion guide.
