what a1c is prediabetes

The A1C test is used to diagnose prediabetes and diabetes. The following ranges are used to determine prediabetes:

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

If your A1C level falls between 5.7% and 6.4%, it indicates prediabetes. This means your blood sugar levels are higher than normal but not high enough to be classified as diabetes. Prediabetes is a warning sign, and lifestyle changes such as diet, exercise, and weight management can help prevent or delay the onset of type 2 diabetes.
