Estimated Average Glucose (eAG)
Estimated Average Glucose (eAG) is calculated from your HbA1c result and represents your approximate average blood sugar level over the past 2 to 3 months. It is not a direct blood glucose measuremen…
Category: Diabetes & Glycemic
Also known as: estimated average glucose, eag, estimated glucose, avg glucose, average glucose, estimated mean glucose, Est. average glucose, Glucose mean value
Reference range: 70–126 mg/dL (Source: ABIM)
Standard unit: mg/dL
High values may indicate
High eAG values correspond to elevated HbA1c and may indicate poorly controlled diabetes or prediabetes.
Low values may indicate
Low eAG values correspond to low HbA1c and are generally normal. Very low values may sometimes indicate frequent hypoglycemia.
Frequently asked questions
- What is a normal Estimated Average Glucose (eAG) level?
- A typical reference range for Estimated Average Glucose (eAG) is 70–126 mg/dL (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is Estimated Average Glucose (eAG) measured in?
- Estimated Average Glucose (eAG) is most commonly reported in mg/dL. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do Estimated Average Glucose (eAG) reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track Estimated Average Glucose (eAG) over time?
- Yes. Upload results from any lab and BloodId charts your Estimated Average Glucose (eAG) over time against its reference range, so you can see whether the trend is rising, falling, or stable.
