A1C to eAG Formula
The estimated Average Glucose (eAG) is calculated from the HbA1c result using the formula derived by the ADAG study group.
eAG (mg/dL) = (28.7 × A1C) - 46.7

| A1C (%) | eAG (mg/dL) | Interpretation |
|---|---|---|
| 5% | 97 | Normal |
| 6% | 126 | Prediabetes |
| 7% | 154 | Diabetes Target |
| 8% | 183 | Elevated |

Example 1
A1C is 6.5%.
- Calculation: (28.7 × 6.5) - 46.7
- 186.55 - 46.7 = 139.85 mg/dL
Example 2
A1C is 9.0%.
- Calculation: (28.7 × 9) - 46.7
- 258.3 - 46.7 = 211.6 mg/dL
How to Use
