A1C chart

The A1C test measures your average blood sugar levels over the past 2-3 months. Here’s a breakdown of the A1C levels and what they mean:

A1C Level (%) Diagnosis Estimated Average Glucose (mg/dL)

Below 5.7 Normal Less than 117
5.7 - 6.4 Prediabetes 117 - 137
6.5 or higher Diabetes 140 or higher

For most people with diabetes, the goal is to maintain an A1C level below 7%. However, your target may vary based on your doctor's recommendations and your overall health.
