Reference values (adults, fasting)
| Fasting glucose | HbA1c | |
|---|---|---|
| Normal | < 100 mg/dL · < 5.6 mmol/L | < 5.7 % |
| Prediabetes | 100–125 mg/dL · 5.6–6.9 mmol/L | 5.7–6.4 % |
| Diabetes | ≥ 126 mg/dL · ≥ 7.0 mmol/L | ≥ 6.5 % |
Formulas: mmol/L = mg/dL ÷ 18.016 · IFCC (mmol/mol) = (HbA1c % − 2.15) × 10.929 · average glucose (mg/dL) = 28.7 × HbA1c % − 46.7 (ADAG study). Thresholds: American Diabetes Association.
