What is the Dexcom G7 CGM System?
Dexcom G7 systems offer a better way to help people gain greater control of their diabetes, so they can more confidently manage it each day. Its low-profile, all-in-one wearable sensor warms up faster than any other CGM on the market,|| sending real-time glucose readings automatically to a compatible smart device* or Dexcom receiver, no fingersticks† required.

 

Dexcom G7 also offers a suite of customizable alerts that can warn of high or low glucose levels and help you spend more time in range.2-6 Industry-leading remote monitoring and reporting capabilities also allow users to stay connected with their loved ones and care teams anytime, anywhere.   

 

†Fingersticks required for diabetes treatment decisions if symptoms or expectations do not match readings.
How long does the Dexcom G7 15 Day CGM sensor last?
The Dexcom G7 15 Day CGM sensor is indicated for 15 days of wear with an additional 12-hour grace period for increased flexibility when changing sensors, for a total of 15.5 days of wear time*.

 

*A study was conducted to assess the sensor life, where 73.9% of sensors lasted the full 15 days. When using the product per the package labeling, approximately 26% of sensors may not last for the full 15 days.
Who is Dexcom G7 system for and the G7 15 Day system for?

Dexcom G7 is for patients two years and older with any type of diabetes, including type 1, type 2, or gestational diabetes.

 

Dexcom G7 15 Day is designed for adults 18 years and older with all types of diabetes, including type 1, type 2, or gestational diabetes.

 

For patients under 18, Dexcom G7 remains the most accurate and powerful CGM system1.

Why isn’t Dexcom G7 15 Day available to pediatric patients?
Dexcom G7 15 Day is currently indicated for use in adults (18+) only, while the current Dexcom G7 CGM system remains the most accurate system1 designed to meet the high demands and specific needs for those under the age of 18 years.

 

In the meantime, we will continue to manufacture, support, and roll out improvements to the Dexcom G7 CGM system (10-day sensor) for its users.

 

We look forward to delivering continued innovation to the Dexcom G7 CGM Systems, focusing on safety, accuracy, and ease of use.

How is the Dexcom G7 15 Day system different from the Dexcom G7 system?
Built on the same platform as the Dexcom G7 system, the Dexcom G7 15 Day CGM connects to the existing ecosystem and uses the Dexcom G7 app, compatible phones, and the Dexcom receiver.

 

The Dexcom G7 15 Day system differs from the Dexcom G7 system in the following ways:
  • Mean absolute relative difference (MARD) accuracy: The Dexcom G7 15 Day system is slightly more accurate with an overall MARD of 8.0%1 compared to the Dexcom G7 system, which holds a MARD of 8.22%
  • Wear time: The Dexcom G7 15 Day sensor has a 15.51* day wear time (includes 12-hour grace period) that is ~50% longer than the 10.5 day wear time (includes 12-hour grace period) of the Dexcom G7 sensor. This means reduced burden from sensor changes, fewer sensor start days, and less waste per month.
  • Age indication: The Dexcom G7 15 Day system is for adults 18 years and older1. The Dexcom G7 system is for patients who are 2 years and older.

 

Beyond these differences, the Dexcom G7 15 Day and Dexcom G7 systems contain the same alert, event logging, and connectivity features.

Why does Dexcom G7 15 Day sensor require a 60-minute warm up?

Dexcom G7 15 Day sensor uses a new algorithm that allows for 5 additional days of wear, currently requiring a 60-minute warm-up.

*Per clinical studies, not all sensors may last 15 days. †A study was conducted to assess the sensor life where 73.9% of sensors lasted the full 15 days. In other words, when using the product per the package labeling, approximately 26% of sensors may not last for the full 15 days. ‡Fingersticks required for diabetes treatment decisions if symptoms or expectations do not match readings.§Excludes implantable CGM systems.
