GMI (Glucose Management Indicator) on Dexcom G7 is a metric that estimates your average A1C level based on continuous glucose monitoring (CGM) data. It provides an approximation of what your lab-measured A1C might be, based on your glucose levels over the past 14 to 90 days.
- How it works: GMI uses the average glucose values from your CGM data to calculate an estimated A1C.
- Purpose: It helps you and your healthcare provider understand how well your blood sugar is managed over time.
- Formula: GMI (%) = 3.31 + 0.02392 × [mean glucose in mg/dL].
GMI is a useful tool for tracking diabetes management, but it should not replace regular A1C tests performed in a lab.
