Clinical takeaway

Anemia, hemoglobin variants, recent transfusion and pregnancy alter the relationship.

When to use

Translate HbA1c into an average glucose patients can relate to.

How it works

eAG (mg/dL) = 28.7 × HbA1c − 46.7; divide by 18 for mmol/L. Reflects mean glucose over ~ 2–3 months.

Key points

  • Anemia, hemoglobin variants, recent transfusion and pregnancy alter the relationship.
  • eAG complements but does not replace day-to-day glucose monitoring.
  • Useful for patient education.
