What does your result mean?
This is your estimated average glucose (eAG) from your A1C.
If you are:
- 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). Keep steady habits: balanced meals with fiber and protein, regular activity, consistent sleep, and periodic glucose checks to confirm you’re not having frequent lows.
- Below range: Your eAG is notably lower than common targets. This can reflect very tight control and may raise the risk of low blood sugar, especially if you use glucose-lowering medications. Spread carbs across meals, pair carbs with protein/fat, carry fast-acting carbs during/after exercise, and monitor for low-glucose symptoms (shakiness, sweating, confusion).
- Above range: Your eAG is above common targets. Focus on: consistent carbohydrate amounts and quality (more fiber, fewer sugary drinks), adding protein/fat to slow spikes, 10–15 minutes of light movement after meals, ~150 minutes/week of moderate exercise plus 2–3 days of resistance training, stress management, and regular sleep. Track patterns (morning vs. post-meal) to guide adjustments.
Note: Targets are guides, not medical advice. Adjust based on your symptoms (e.g., signs of lows or highs like excessive thirst or frequent urination) and your 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 average glucose over roughly the past 2–3 months.
Sized to you
- The estimate depends only on your A1C and chosen units; it doesn’t use age, sex, or body size. Factors that change red blood cell lifespan (e.g., anemia, recent blood loss, kidney disease, pregnancy, some hemoglobin variants) can make A1C differ from your true average glucose.
Activity adjustment
- The equation itself doesn’t adjust for workouts. Regular physical activity and improved fitness tend to lower true average glucose over weeks, which can lower A1C and eAG over time.
Environment & day-to-day
- Stress, illness, certain medications (e.g., steroids), sleep debt, menstrual cycle, and major diet changes can shift daily glucose and, over weeks, your A1C. Temperature extremes and altitude can also influence measured glucose in some devices.
Why a range?
- Glucose fluctuates from moment to moment, and the A1C-to-eAG relationship varies among individuals. Two people with the same A1C can have different average patterns. A range better reflects normal biological variability and measurement uncertainty.
