What does your result mean?
This is your estimated average glucose (eAG) derived from your A1C result.
In range
Your eAG is at or below a commonly used A1C goal for many adults (A1C <7%, ≈ eAG <154 mg/dL or <8.6 mmol/L). Maintain steady habits with:
- Balanced meals with fiber and protein
- Regular physical activity
- Consistent sleep patterns
- Periodic glucose checks to ensure you’re not experiencing frequent lows
Below range
Your eAG is notably lower than common targets. This may indicate very tight glucose control and a higher risk of low blood sugar, especially if you use glucose-lowering medications. Consider:
- Spreading carbohydrates evenly across meals
- Pairing carbs with protein and healthy fats
- Carrying fast-acting carbs during or after exercise
- Monitoring for low-glucose symptoms (e.g., shakiness, sweating, confusion)
Above range
Your eAG is above common targets. To improve control, focus on:
- Consistent carbohydrate amounts and higher-fiber food choices
- Adding protein or fat to meals to slow glucose spikes
- Engaging in 10–15 minutes of light movement after meals
- Aiming for ~150 minutes of moderate exercise per week plus 2–3 resistance sessions
- Managing stress and maintaining regular sleep
- Tracking glucose patterns (morning vs. post-meal) to guide adjustments
Note: These targets are general guides, not medical advice. Always consider your symptoms (e.g., excessive thirst, frequent urination, or signs of low blood sugar) and personal health circumstances.
How is this calculated?
Evidence baseline
Uses the ADAG/ADA relationship between A1C and average glucose:
eAG (mg/dL) = 28.7 × A1C(%) − 46.7
eAG (mmol/L) = mg/dL ÷ 18
A1C reflects your average glucose over the past 2–3 months.
Sized to you
The estimate depends only on your A1C and selected units; it doesn’t use age, sex, or body size. Conditions that alter red blood cell lifespan (such as anemia, recent blood loss, kidney disease, pregnancy, or certain hemoglobin variants) can affect accuracy.
Activity adjustment
The formula itself doesn’t account for exercise. However, regular activity and improved fitness tend to lower true average glucose and, over time, your A1C and eAG.
Environment & day-to-day factors
Stress, illness, certain medications (like steroids), sleep deprivation, menstrual cycle changes, and diet shifts can all affect daily glucose and long-term A1C. Temperature extremes and altitude may also influence glucose readings on some devices.
Why a range?
Glucose naturally fluctuates, and the A1C-to-eAG relationship varies between individuals. Two people with the same A1C can have different glucose patterns. Expressing results as a range better reflects biological variability and measurement uncertainty.
