GMI stands for Glucose Management Indicator, which is a metric used to estimate your average blood glucose levels over the past 2-3 months. It is derived from continuous glucose monitoring (CGM) data and is similar to the A1C test, but it provides a more personalized and real-time view of your glucose levels.

  • How GMI is Calculated: GMI is calculated using the average glucose levels from CGM data. The formula is:

    GMI (%) = 3.31 + 0.02392 × (average glucose in mg/dL)

  • Comparison to A1C: While A1C measures the percentage of glycated hemoglobin in your blood, GMI reflects your average glucose levels based on CGM data. GMI can be more accurate for individuals with conditions that affect red blood cell turnover, such as anemia.

  • Why GMI Matters: GMI helps people with diabetes understand how well their blood sugar is managed and can guide adjustments in treatment plans.
