What does the Estimated Average Glucose test measure?

Q: What is the reference range for Estimated Average Glucose?

The standard reference range for Estimated Average Glucose is Derived from HbA1c; an HbA1c of 5.7% corresponds to ~117 mg/dL and 6.5% to ~140 mg/dL # REVIEWER FLAG: eAG is calculated from HbA1c via the ADAG equation — confirm LabCorp uses the standard formula.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Estimated Average Glucose (eAG) is a clinical biomarker used in metabolic-diabetes assessment. Estimated average glucose is a calculated value derived directly from HbA1c using the validated ADAG relationship, expressing the HbA1c result in the same glucose units patients see on home meters. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Estimated Average Glucose?

Estimated average glucose is a calculated value derived directly from HbA1c using the validated ADAG relationship, expressing the HbA1c result in the same glucose units patients see on home meters. It is not a separately measured analyte but a translation of HbA1c intended to make chronic glycaemic control more intuitive.

Why is Estimated Average Glucose measured?

eAG helps practitioners and patients relate the HbA1c percentage to familiar day-to-day glucose readings, supporting communication and self-management. Because it is derived from HbA1c, it carries the same strengths and limitations and adds no independent information beyond presenting the result in glucose units.
