what is considered high hemoglobin a1c

Hemoglobin A1C (HbA1c) levels are used to diagnose and monitor diabetes and prediabetes. The following ranges are generally considered:

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

For people with diabetes, the target A1C level is typically 7% or less, though this may vary based on individual health conditions and doctor recommendations. Higher A1C levels indicate poorer blood sugar control and are associated with an increased risk of diabetes complications.

If your A1C is high, consult your healthcare provider to adjust your diabetes management plan.
