GMI (Glucose Management Indicator) is an estimate of your A1C level based on continuous glucose monitoring (CGM) data. It provides an approximation of what your A1C might be if you were to take a lab test.

  • Normal GMI Range: Typically, a normal GMI is considered to be below 5.7%, which aligns with the normal A1C range for individuals without diabetes.
  • Prediabetes Range: A GMI between 5.7% and 6.4% may indicate prediabetes.
  • Diabetes Range: A GMI of 6.5% or higher suggests diabetes.

GMI is a useful tool for people using CGM to track their glucose levels over time and make informed decisions about their diabetes management.
