what is a normal number 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. For most people with diabetes, the target A1C level is 7% or less, but your doctor may set a different goal based on your individual health needs.
