An A1C-like estimate derived from adequately covered CGM data, not a diagnosis or an estimate validated for sparse manual logs.
The Glucose Management Indicator converts your mean glucose into an A1C-style percentage using a published formula (GMI = 3.31 + 0.02392 × mean mg/dL). It lets you see a familiar number between lab visits.
GMI and a lab A1C often differ by a few tenths of a percent; they measure related but not identical things. A gap between them is normal and can itself be informative.
Learn what the reference numbers mean, then track your own logged readings and their share in your selected range. GMI and estimated A1C are withheld when source and coverage are unvalidated.
