Know your eAG. Know your health.
Test your Estimated Average Glucose and 100+ other biomarkers in a single blood draw.
Normal range: 0 – 117 mg/dL (lower is better)
Estimated average glucose (eAG) translates your HbA1c into the same units you see on a glucose meter (mg/dL). It represents your average blood sugar over the past 2-3 months, expressed as a single everyday number rather than a percentage. An HbA1c of 5.6% works out to an eAG of about 114 mg/dL, while a 7% HbA1c corresponds to roughly 154 mg/dL. Because it uses familiar units, eAG makes it easier to connect your long-term control to the daily readings you might see at home.
A normal eAG is 0 – 117 mg/dL. Lower is better.
Since eAG is calculated directly from HbA1c, anything that raises HbA1c raises eAG: chronically high blood sugar from insulin resistance, prediabetes, or diabetes. A diet high in refined carbohydrates and sugar, combined with physical inactivity and excess weight, is the most common pattern.
Conditions that change red blood cell lifespan can distort the estimate, since HbA1c depends on how long red cells survive. Iron deficiency anemia can falsely raise it, while conditions that shorten red cell life can falsely lower it.
The same lifestyle changes that improve HbA1c lower eAG: regular exercise, weight loss, reducing refined carbs and sugar, eating more fiber, and getting adequate sleep. Because it reflects a 2-3 month average, changes take time to show up.
eAG comes in a comprehensive metabolic panel (about $29–$55). Empirical's $190 panel adds HbA1c, Glucose, and 100+ other biomarkers.
