Get tested with Superpower

If you’ve been postponing blood testing for years or feel frustrated by doctor appointments and limited lab panels, you are not alone. Standard healthcare is often reactive, focusing on testing only after symptoms appear or leaving patients in the dark.

Superpower flips that approach. We give you full insight into your body with over 100 biomarkers, personalized action plans, long-term tracking, and answers to your questions, so you can stay ahead of any health issues.

With physician-reviewed results, CLIA-certified labs, and the option for at-home blood draws, Superpower is designed for people who want clarity, convenience, and real accountability - all in one place.

Key benefits of Estimated Average Glucose (mg/dL) testing

• Shows your average blood sugar over the past 2–3 months.
• Flags early diabetes risk before symptoms appear or complications develop.
• Tracks how well diet, exercise, or medication control your glucose levels.
• Guides treatment adjustments to prevent nerve, kidney, and heart damage.
• Clarifies fatigue, thirst, or blurred vision tied to high blood sugar.
• Protects pregnancy outcomes by identifying glucose imbalance before conception or during gestation.
• Best interpreted with HbA1c and fasting glucose for complete metabolic insight.

What is Estimated Average Glucose (mg/dL)?

Estimated average glucose (eAG) is a calculated value that translates your hemoglobin A1c result into the same units your home glucose meter uses. It represents the average level of sugar circulating in your bloodstream over the past two to three months.

Your blood sugar story in familiar numbers

eAG doesn't come from a separate blood test. Instead, it's derived mathematically from hemoglobin A1c, which measures how much glucose has attached to your red blood cells over their lifespan. Because A1c is reported as a percentage, eAG converts that percentage into milligrams per deciliter (mg/dL), the format most people recognize from daily glucose monitoring.

A bridge between lab results and daily experience

This conversion helps you connect long-term glucose control with the numbers you see day to day. If your eAG is 154 mg/dL, for example, it means your average blood sugar over recent months has hovered around that level, even though individual readings fluctuate higher and lower throughout each day.

Why is Estimated Average Glucose (mg/dL) important?

Estimated Average Glucose translates your hemoglobin A1c into a three-month average blood sugar level, offering a window into how well your body manages fuel around the clock. It reflects the balance between insulin action, carbohydrate intake, liver glucose output, and cellular uptake. This single number reveals whether your metabolism is running smoothly or straining under chronic glucose excess.

When your average glucose runs too low

Values consistently below 100 mg/dL may signal overly aggressive glucose control or inadequate carbohydrate availability. You might experience fatigue, shakiness, difficulty concentrating, or irritability as your brain and muscles struggle for fuel. In people taking diabetes medications, this pattern raises the risk of dangerous hypoglycemic episodes.

When your average glucose climbs too high

Readings above 154 mg/dL correspond to prediabetes or diabetes and indicate that glucose is lingering in your bloodstream instead of entering cells efficiently. Over time, this excess sugar damages blood vessel linings, nerves, kidneys, and the retina. You may notice increased thirst, frequent urination, blurred vision, slow wound healing, and persistent fatigue as your tissues cope with both energy deprivation and toxic sugar exposure.

The metabolic ripple effect

Estimated Average Glucose connects directly to cardiovascular risk, kidney function, nerve health, and inflammatory tone. Keeping it in a healthy range protects your eyes, heart, and brain while preserving energy and resilience across decades.

What do my Estimated Average Glucose (mg/dL) results mean?

Low estimated average glucose values

Low values usually reflect consistently tight glucose control over the preceding two to three months. This occurs when hemoglobin A1c is below typical thresholds, translating to an estimated average glucose below approximately 100 mg/dL. In people without diabetes, this is generally physiologic. In those treated with insulin or glucose-lowering medications, it may signal frequent or unrecognized hypoglycemia, which can impair awareness and increase risk of severe low blood sugar episodes.

Optimal estimated average glucose values

Being in range suggests stable glucose metabolism and appropriate insulin function. For most adults without diabetes, optimal estimated average glucose sits between roughly 100 and 120 mg/dL, corresponding to hemoglobin A1c values in the low-to-mid normal range. This reflects balanced fuel delivery to tissues and minimal glycemic variability, supporting metabolic health and reducing long-term vascular stress.

High estimated average glucose values

High values usually reflect sustained hyperglycemia, indicating impaired insulin secretion, insulin resistance, or both. Estimated average glucose above 125 mg/dL suggests prediabetes or diabetes, depending on corresponding A1c thresholds. Chronic elevation drives nonenzymatic glycation of proteins throughout the body, contributing to microvascular and macrovascular complications over time.

Factors that influence estimated average glucose interpretation

Estimated average glucose is derived mathematically from hemoglobin A1c and assumes normal red blood cell lifespan. Conditions that alter red cell turnover, such as anemia, hemoglobinopathies, or recent transfusion, can affect accuracy. Pregnancy and certain medications may also influence A1c independently of true glucose exposure.
