The method to estimate average glucose levels from A1C results is grounded in the established relationship between hemoglobin A1C levels and mean blood glucose levels. The correct calculation is based on the formula eAG (estimated Average Glucose) = (28.7 x A1C) - 46.7.

This formula derives from research that identifies the correlation between the percentage of A1C and the average daily glucose levels over the preceding two to three months. The coefficients in this formula were determined through studies that collected data on A1C values and corresponding average glucose measurements, allowing for a reliable conversion.

Using this formula, healthcare professionals can effectively translate A1C results, expressed as a percentage, into more understandable glucose values presented in mg/dL, which patients can relate to their daily glucose monitoring results. This can enhance patient education and self-management by providing a clearer picture of how their A1C relates to their daily glucose levels.

Understanding this formula is crucial for diabetes educators, as it helps in communication and reinforces the significance of maintaining blood sugar levels within target ranges for effective diabetes management.
