Frequently asked questions
What is estimated average glucose (eAG)?
eAG converts your A1C percentage into the average blood-sugar number (mg/dL or mmol/L) it reflects over the past 2–3 months, so it's easier to relate to home glucose readings.
Is a lower A1C always better?
Lower usually means better long-term control, but targets are personal. Very low numbers can mean low blood sugar. Discuss your goal A1C with your doctor.
