what hemoglobin a1c is prediabetes

Hemoglobin A1C (HbA1c) levels are used to diagnose prediabetes and diabetes. According to the CDC and other health organizations:

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

If your A1C falls between 5.7% and 6.4%, it indicates prediabetes, which 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.
