From A1c to eAG: A Simple Way to Understand Your Average Glucose
Understanding your blood glucose levels is essential, especially if you're managing diabetes or are at risk of developing it. Two common terms you'll encounter are A1c and eAG (estimated Average Glucose). While they both provide insights into your glucose control, they represent slightly different aspects. This article aims to simplify the relationship between A1c and eAG, offering you a straightforward way to interpret your results and improve your health.
What is A1c?
The A1c test, also known as the hemoglobin A1c test, measures your average blood sugar levels over the past 2-3 months. Here’s how it works:
- Glucose in your bloodstream attaches to hemoglobin, a protein in red blood cells that carries oxygen.
- The higher your blood sugar levels, the more glucose attaches to the hemoglobin.
- The A1c test measures the percentage of hemoglobin that has glucose attached to it.
Therefore, A1c provides a long-term view of your glucose control, as red blood cells live for about three months.

Why is A1c Important?
- Diagnosis: A1c is used to diagnose prediabetes and diabetes.
- Management: It helps people with diabetes monitor how well their treatment plan is working.
- Risk Assessment: It provides an indicator of the risk of developing diabetes-related complications, such as kidney disease, nerve damage, and eye damage.
What is eAG (estimated Average Glucose)?
Estimated Average Glucose (eAG) is another way to express your average blood sugar level over a period of time. However, instead of a percentage like A1c, eAG is reported in the same units that you see on your blood glucose meter—milligrams per deciliter (mg/dL). The eAG value is calculated from your A1c result using a formula to convert the A1c percentage into a more easily understandable average glucose level.
Why is eAG Useful?
- Simplicity: eAG translates A1c results into a format familiar to most people with diabetes, making it easier to understand and track.
- Comparison: It allows a direct comparison between your daily glucose readings and your long-term average.
- Enhanced Understanding: By seeing your average glucose in mg/dL, you can get a better sense of how your daily lifestyle choices, medication, and diet affect your overall glucose control.
The Relationship Between A1c and eAG
A1c and eAG are essentially two different ways of presenting the same information: your average blood glucose levels over the past 2-3 months. The conversion formula ensures that there’s a direct correlation between the two. Understanding this relationship can make managing your diabetes more intuitive.
Here's a common conversion chart:
| A1c (%) | eAG (mg/dL) | eAG (mmol/L)* |
|---|---|---|
| 6.0 | 126 | 7.0 |
| 6.5 | 140 | 7.8 |
| 7.0 | 154 | 8.6 |
| 7.5 | 169 | 9.4 |
| 8.0 | 183 | 10.1 |
| 8.5 | 197 | 10.9 |
| 9.0 | 212 | 11.8 |
Note: mmol/L (millimoles per liter) is a different unit of measurement commonly used outside the US.
As you can see, a higher A1c percentage corresponds to a higher eAG in mg/dL, indicating poorer average glucose control.
Interpreting Your Results
Understanding what your A1c and eAG values mean is crucial for managing your health. Here’s a simple guide:

A1c Targets
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
- Target for most adults with diabetes: Below 7.0% (Individual targets may vary based on your health condition, age, and other factors; always follow your doctor’s recommendations)
eAG Targets
- eAG Corresponding to A1c of 7.0%: Approximately 154 mg/dL
- General Target for people with diabetes: 80-130 mg/dL before meals and less than 180 mg/dL 1-2 hours after starting a meal. (Again, targets can vary, consult your healthcare provider.)
Actions to Take
- Consult Your Doctor: Discuss your A1c and eAG results with your healthcare provider to understand their implications fully.
- Adjust Your Treatment Plan: Based on your results, your doctor may adjust your medication, diet, or exercise regimen.
- Monitor Your Blood Glucose Regularly: Frequent blood glucose monitoring can provide real-time feedback and help you make informed decisions about your daily care.
- Maintain a Healthy Lifestyle: A balanced diet, regular physical activity, and maintaining a healthy weight are essential for managing blood glucose levels.
- Use a Continuous Glucose Monitor (CGM)**: If your doctor recommends it, using a CGM can provide detailed insights into your glucose patterns, making it easier to identify trends and adjust your management plan.
Factors That Can Affect A1c Results
It's important to be aware that certain conditions can affect the accuracy of the A1c test:
- Anemia: Conditions like iron deficiency anemia can falsely lower A1c levels.
- Hemoglobin Variants: Certain hemoglobin variants (e.g., sickle cell trait) can interfere with A1c test results.
- Kidney Disease: Kidney disease can affect red blood cell lifespan and influence A1c values.
- Pregnancy: A1c levels may be lower during pregnancy due to increased red blood cell turnover.
If you have any of these conditions, be sure to inform your doctor, as they may need to use alternative methods to assess your average blood glucose.
Practical Tips for Improving Your A1c and eAG

Improving your A1c levels (and consequently your eAG) involves making sustainable lifestyle changes. Here are some practical tips:
- Dietary Modifications: Focus on a balanced diet rich in fruits, vegetables, lean proteins, and whole grains. Limit processed foods, sugary drinks, and excessive carbohydrates. Consult a registered dietitian for personalized meal planning.
- Regular Exercise: Aim for at least 150 minutes of moderate-intensity exercise per week, such as brisk walking, cycling, or swimming. Regular physical activity helps improve insulin sensitivity and lowers blood glucose levels.
- Medication Adherence: If you are prescribed medication for diabetes, take it as directed by your doctor. Consistency is key for maintaining stable blood glucose levels.
- Stress Management: Practice relaxation techniques such as yoga, meditation, or deep breathing exercises to manage stress levels. Stress can impact blood glucose control.
- Adequate Sleep: Aim for 7-8 hours of quality sleep each night. Poor sleep can affect hormone levels that regulate blood sugar.
- Hydration: Drink plenty of water throughout the day to help your kidneys flush out excess glucose.
Conclusion
Understanding the relationship between A1c and eAG is crucial for managing blood glucose effectively. While A1c provides a long-term view as a percentage, eAG translates this into a more familiar glucose level (mg/dL), making it easier to track and interpret your results. By understanding these metrics and implementing healthy lifestyle changes, you can take control of your diabetes management and improve your overall health. Always consult with your healthcare provider for personalized advice and treatment plans.
