what's the normal range for hemoglobin

The normal range for hemoglobin A1C (HbA1c) levels, which reflect average blood sugar levels over the past 2-3 months, is as follows:

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

These ranges are used to diagnose prediabetes and diabetes and to monitor blood sugar management in individuals with diabetes. For most people with diabetes, the target A1C level is less than 7%, but your doctor may set a different goal based on your health condition.
