what do the a1c numbers mean

The A1C test measures your average blood sugar levels over the past 2-3 months. The results are reported as a percentage, and the ranges are used to diagnose prediabetes and diabetes:

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

For people with diabetes, the A1C test also helps monitor how well their blood sugar is being managed. The goal for most adults with diabetes is to keep their A1C level below 7%, but this target may vary based on individual health conditions.

Here’s a quick reference table for A1C and estimated average glucose (eAG):

A1C % eAG (mg/dL)

6 126
7 154
8 183
9 212
10 240

Higher A1C levels are linked to an increased risk of diabetes complications, so maintaining your target A1C is crucial for long-term health.
