what is normal a1c blood sugar level

The A1C test measures your average blood sugar levels over the past 2-3 months. Here are the standard ranges for A1C levels:

A1C Level (%) Classification

Below 5.7 Normal
5.7 - 6.4 Prediabetes
6.5 or higher Diabetes

• Normal: Below 5.7% indicates healthy blood sugar control.
• Prediabetes: 5.7% to 6.4% suggests an increased risk of developing diabetes.
• Diabetes: 6.5% or higher typically indicates diabetes.

For most people with diabetes, the target A1C level is below 7%, but your doctor may set a different goal based on your health condition.
