What is my estimated average glucose from my A1C?
Estimated Average Glucose
–mg/dL
Assumptions & limitations:
- Uses the ADAG study regression formula: eAG (mg/dL) = 28.7 × A1C − 46.7.
- A1C reflects your average blood glucose over roughly the prior 2–3 months — it is not a single-moment glucose reading.
- Results are an estimate. Day-to-day glucose can vary from eAG based on individual factors.
