Accuracy of the 15.5-day G7 integrated continuous glucose monitor in adults with diabetes

In a new study in the peer-reviewed journal Diabetes Technology & Therapeutics (DTT), investigators evaluated the accuracy of the 15.5-day Dexcom G7 integrated continuous glucose monitor (CGM) in adults with diabetes. Click here to read the article now.

The study enrolled 130 adults at six centers in the U.S. with either type 1 (87%) or type 2 diabetes on MDI (6%) or basal insulin only (7%) and analyzed CGM-venous (YSI) blood matched pairs (20,310), with participants using the 15-day Dexcom G7 CGM device.

Satish Garg, MD, from the University of Colorado Denver and Editor-in-Chief of Diabetes Technology & Therapeutics, and coauthors, reported that “The device exceeded iCGM performance goals and user experiences were broadly positive. No serious adverse events were reported.”

Accuracy evaluations included the mean absolute relative difference (MARD), which was 8.0%. This is the lowest reported MARD in a study designed to the U.S. Food and Drug Administration’s iCGM criteria.

“We conclude that the Dexcom 15-day G7 CGM is accurate and safe for use up to 15.5 days in adults with diabetes with a 27-minute warm-up,” stated the investigators.
