Using the HbA1c to estimated mean plasma glucose conversion, what is the approximate mean plasma glucose for an HbA1c of 7%?

Explanation:
The estimated mean plasma glucose (eAG) is found using the conversion eAG = 28.7 × HbA1c − 46.7. For an HbA1c of 7%, compute 28.7 × 7 = 201, then 201 − 46.7 ≈ 154 mg/dL. So the mean plasma glucose corresponding to HbA1c 7% is about 154 mg/dL. This translates the HbA1c percentage into a familiar daily glucose level. The other numbers don’t align with the same calculation (they’re closer to different HbA1c values), so 154 mg/dL is the correct interpretation for 7%.
