what is a good average glucose number

A good average glucose number, as measured by the A1C test, typically falls within the following ranges:

• Normal: Below 5.7%
• Prediabetes: 5.7% to 6.4%
• Diabetes: 6.5% or above

For most people with diabetes, the target A1C level is 7% or less, which corresponds to an estimated average glucose (eAG) of about 154 mg/dL. However, individual targets may vary based on factors like age, overall health, and medical history. Always consult your healthcare provider to determine the best target for you.

Here’s a quick reference table for A1C and eAG:
