The Dexcom G7 15 Day 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.

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 15.5^1* 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^1,2.

The Dexcom G7 15 Day Continuous Glucose Monitoring (Dexcom G7 15 Day) System is Dexcom’s newest, longest-lasting^{*, †,1}, and most accurate¹ continuous glucose monitoring (CGM) system. It is designed to provide real-time glucose readings for an industry-leading^*,1 15.5 days^†.

The Dexcom G7 15 Day CGM is a small, wearable sensor that sends accurate, real-time glucose readings to the Dexcom G7 Continuous Glucose Monitoring (Dexcom G7) System app or receiver every five minutes. No fingersticks^§ or scanning required.
 

Your patients will see their glucose trends right on their phone^‡, making it easier to make better diabetes management decisions^||. CGM use is proven to lower A1C and increase time in range^2-6.

All Dexcom G7 CGM Systems also offer customizable alerts that can warn of high or low glucose levels and allow you to share your glucose numbers with your followers^¶. The Dexcom G7 15 Day system is also part of the most connected CGM in the world⁷ with real-time connectivity that can drive automated insulin delivery (AID) systems, connect with wearables like Apple Watch^®#, and integrate with popular digital health apps.

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

Dexcom G7 15 Day differs from Dexcom G7 in three ways: 

• MARD Accuracy – Dexcom G7 15 Day is slightly more accurate with a MARD of 8.0%¹ compared to Dexcom G7 which holds a MARD of 8.2%²
• Wear Time – Dexcom G7 15 Day sensor has a 15.5* (includes 12-hour grace period) day wear time that is ~50% longer than Dexcom G7’s 10.5 (includes 12-hour grace period) day wear time. This means reduced burden for your patients from less sensor changes, less day ones, and less waste per month.
• Age Indication – Dexcom G7 15 Day is for adults age 18+. Dexcom G7 is for patients who are ages 2 and older. Dexcom recommends adults 18+ use Dexcom G7 15 Day for the wear time benefits. 

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