what is normal hba1c by age

The normal HbA1c levels generally do not vary significantly by age. However, target ranges may differ based on individual health conditions and recommendations from healthcare providers. Here are the general guidelines:

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

For most adults with diabetes, the target HbA1c level is less than 7%. However, older adults or those with other health complications may have slightly higher targets to avoid the risk of hypoglycemia. Always consult your healthcare provider for personalized goals.
