what is mean glucose

Mean glucose refers to the average blood sugar level over a specific period, typically measured over 90 days. It is often calculated using data from continuous glucose monitors (CGMs) or estimated from the A1C test, which reflects your average blood glucose levels over the past 2-3 months.

Here’s a quick reference table for A1C and estimated average glucose (eAG):

A1C (%) eAG (mg/dL)

6 126
7 154
8 183
9 212
10 240

Understanding your mean glucose helps in managing diabetes effectively and reducing the risk of complications.
