The U.S. Food and Drug Administration has cleared the Dexcom G7 15-day Continuous Glucose Monitor (CGM) to patients with diabetes over the age of 18. This is the longest continuous system on the market.
The G7 15-day sensor builds on the technology and performance of the Dexcom G7 CGM, which has been shown to reduce A1C and reduce hyperglycemia and hypoglycemia. However, it only has 10 days of life. The G7 15-day sensor provides five days that make diabetes management easier, while there is less sensor exchange per month.
According to Dexcom, it is also the most accurate system. The overall average absolute relative difference or MARD of the G7 15-day sensor is 8.0%. The frequency of MARD measuring the readings of a CGM sensor is different from the blood sugar test. The Dexcom G7 sensor has a MARD score of 8.2%. The sensor sends real-time glucose readings to the Dexcom G7 app every five minutes.
Continuous glucose monitors have replaced fingerprints for many people and allow you to monitor your blood sugar levels in real time. Dexcom has been a leading brand of glucose biosensing for the past 25 years. Last year, Dexcom received the first over-the-counter CGM FDA clearance in the Stelo Glucose BioSensor system.
What does this sensor mean to you
This advance marks a step in diabetes management. There is another five days of sensor life that can reduce waste and give you more control over diabetes before you have to swap.
You will see several features on the G7 platform, such as waterproofing, automated activities, and simplified meal and medication logging. The G7 will also be connected to your Apple Watch to monitor your glucose levels without the need for a phone to turn off.
The impact is not limited to your ability to track numbers. You can also share glucose numbers with loved ones and caregivers through existing applications, although you need to connect to the Internet on a compatible device to send data. According to the DEXCOM website data, there are 10 followers restrictions on sharing. The Dexcom Clarity app integration allows your doctor to view your reading, although you must first authorize sharing with your clinic.
FDA gap means Dexcom can work to ensure the G7 15-day sensor is compatible with the insulin pump. According to this version, the G7 15-day sensor is expected to be released in the second half of 2025. A new prescription for the G7 15-day sensor will be required. The price will depend on your coverage, although according to Dexcom, it should be about the same monthly fee as the Dexcom G7.
