To estimate your A1C level from your average blood glucose (BG) readings, you can use the following formula:
A1C (%) = (Average BG + 46.7) / 28.7
For example, if your average blood glucose is 154 mg/dL, your estimated A1C would be:
(154 + 46.7) / 28.7 = 7.0%
Here’s a quick reference table for common blood glucose levels and their corresponding A1C estimates:
Average Blood Glucose (mg/dL) Estimated A1C (%)
126 6.0
154 7.0
183 8.0
212 9.0
240 10.0
This formula provides an approximation and should not replace a lab-tested A1C result. Always consult your healthcare provider for accurate diagnosis and management.
