The Glucose Management Indicator (GMI) is a feature on the Dexcom G7 continuous glucose monitoring (CGM) system that approximates the laboratory A1C level expected based on average glucose measured using CGM values. The GMI is derived from at least 12 days of CGM data and may be similar to, higher than, or lower than the laboratory A1C. Differences between GMI and laboratory A1C may reflect differences among an individual’s red blood cell lifespan, how glucose binds to hemoglobin, or due to a recent fluctuation in glucose control. The GMI provides an estimated A1C level based on continuous glucose monitoring data and can avoid some of the limitations of A1C tests. The GMI is shown on the Dexcom G7 Clarity Card, which is a Clarity data summary that also includes average glucose and time in range for the past 3, 7, 14, 30, or 90 days/cgm-selection-training/dexcom-g7-libre-3-comparison).
