To estimate your average blood glucose (eAG) from your A1C percentage, you can use the following formula:
eAG (mg/dL) = (28.7 × A1C) - 46.7
For example, if your A1C is 7%, your estimated average glucose would be:
(28.7 × 7) - 46.7 = 154 mg/dL
Here’s a quick reference table for common A1C values:
A1C (%) Estimated Average Glucose (mg/dL)
5 97
6 126
7 154
8 183
9 212
10 240
This formula provides an approximation of your average blood glucose levels over the past 2-3 months, as reflected by your A1C test. However, individual variations may occur, so always consult your healthcare provider for personalized advice.
