No, GMI (Glucose Management Indicator) and A1C (Hemoglobin A1C) are not the same, although they are related. Here’s a breakdown:
- A1C: Measures the percentage of hemoglobin in your blood that has glucose attached to it. It reflects your average blood sugar levels over the past 2-3 months.
- GMI: An estimated value derived from continuous glucose monitoring (CGM) data. It predicts what your A1C might be based on your average glucose levels over a shorter period (typically 14-30 days).
While GMI can provide a close estimate of A1C, it is not a direct replacement. A1C remains the gold standard for diagnosing and monitoring diabetes.
