what is normal average glucose

Normal average glucose levels can be estimated using the A1C test, which reflects your average blood sugar levels over the past 2-3 months. Here’s a breakdown of normal and abnormal ranges:

A1C % Estimated Average Glucose (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 without diabetes, a normal A1C level is below 5.7%, which corresponds to an average glucose level of less than 117 mg/dL. If your A1C is higher, it may indicate prediabetes or diabetes. Always consult your healthcare provider for personalized advice.
