what is a healthy average glucose

A healthy average glucose level, as measured by the A1C test, is typically below 5.7%. This corresponds to an estimated average glucose (eAG) of less than 117 mg/dL. Here’s a breakdown of the ranges:

A1C (%) eAG (mg/dL) Condition

Below 5.7 Below 117 Normal
5.7–6.4 117–137 Prediabetes
6.5 or above 140 or above Diabetes

For most people with diabetes, the target A1C level is less than 7%, which corresponds to an eAG of about 154 mg/dL. However, individual targets may vary based on factors like age, medical history, and other health conditions. Always consult your healthcare provider for personalized goals.
