GMI, or Glucose Management Indicator, 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, which measures the percentage of glycated hemoglobin in your blood.
-
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)
-
Purpose: GMI helps individuals with diabetes understand how well their blood sugar is managed over time, similar to A1C but based on real-time glucose data.
-
Comparison to A1C: While A1C reflects blood sugar levels over 2-3 months, GMI provides a more immediate and dynamic view based on CGM data. However, GMI and A1C may not always match due to differences in how they are measured.
-
Use in Diabetes Management: GMI is particularly useful for people using CGM devices to track their glucose levels and adjust their diabetes management plan accordingly.
