what is a normal estimated average glucose

The estimated average glucose (eAG) is a way to interpret your A1C results in terms of everyday blood sugar levels. It provides an average blood glucose level over the past 2-3 months. Here’s a general guide:

A1C (%) eAG (mg/dL)

6 126
7 154
8 183
9 212
10 240

• Normal: An A1C below 5.7% corresponds to an eAG of less than 117 mg/dL.
• Prediabetes: An A1C between 5.7% and 6.4% corresponds to an eAG of 117–137 mg/dL.
• Diabetes: An A1C of 6.5% or higher corresponds to an eAG of 140 mg/dL or higher.

For most people with diabetes, the goal is to maintain an A1C below 7%, which corresponds to an eAG of 154 mg/dL or less. However, individual targets may vary based on your doctor's recommendations.
