The Ultimate Guide to A1c: Levels, Chart, and Conversion to eAG
Understanding your A1c level is essential for managing diabetes and maintaining optimal health. This comprehensive guide breaks down everything you need to know about A1c, including what it is, healthy ranges, an A1c chart, and how it converts to estimated average glucose (eAG). We'll also explore factors that can affect A1c results and strategies for improving your A1c levels.
What is A1c?
A1c, also known as hemoglobin A1c, is a blood test that provides an average of your blood sugar levels over the past 2-3 months. Unlike a regular blood glucose test that shows your blood sugar at a specific moment, A1c gives a broader picture of your blood sugar control. Specifically, A1c measures the percentage of your hemoglobin (the protein in red blood cells that carries oxygen) that has glucose attached to it. The higher your blood sugar levels, the more glucose attaches to your hemoglobin, resulting in a higher A1c percentage. It’s a crucial tool for diagnosing prediabetes, diabetes, and monitoring the effectiveness of diabetes treatment plans.
Why is A1c Important?
Regular A1c testing is vital for several reasons:
- Diagnosis: A1c is a key diagnostic test for prediabetes and type 2 diabetes.
- Monitoring: For individuals with diabetes, A1c helps monitor how well their treatment plan is working. It allows healthcare providers to adjust medications, lifestyle interventions, or both to better manage blood sugar levels.
- Long-Term Health: Maintaining healthy A1c levels reduces the risk of long-term complications associated with diabetes, such as nerve damage (neuropathy), kidney disease (nephropathy), eye damage (retinopathy), and cardiovascular disease.
- Motivation: Tracking A1c provides feedback, motivating individuals to adhere to their treatment plan and make positive lifestyle changes.
A1c Levels Chart: Understanding Your Results
Here’s a simple chart to help you understand what your A1c results mean. Remember, these values are general guidelines, and your target A1c may vary based on individual factors and your doctor's recommendations.
| A1c Level | Category | Implication |
|---|---|---|
| Below 5.7% | Normal | Indicates normal blood sugar levels. |
| 5.7% to 6.4% | Prediabetes | Indicates a higher risk of developing type 2 diabetes. Lifestyle changes can help prevent progression. |
| 6.5% or higher | Diabetes | Indicates diabetes. Treatment and management are required. |
| For People with Diabetes: Below 7% (General Goal) | Good Control | Generally considered a good target for people with diabetes to reduce risk of complications. |
A1c to eAG Conversion: Understanding the Relationship
eAG (estimated Average Glucose) is another way to express your average blood sugar levels. It’s directly related to your A1c and provides a more relatable number, similar to what you see on your glucose meter. The A1c to eAG conversion allows you to understand what your A1c percentage translates to in terms of average blood glucose levels in mg/dL (milligrams per deciliter).
How to Convert A1c to eAG
The formula to convert A1c to eAG is:
- eAG (mg/dL) = (28.7 x A1c) - 46.7

Using this formula, we can create a simple conversion table:
| A1c (%) | eAG (mg/dL) | eAG (mmol/L) * |
|---|---|---|
| 6% | 126 | 7.0 |
| 7% | 154 | 8.6 |
| 8% | 183 | 10.2 |
| 9% | 212 | 11.8 |
| 10% | 240 | 13.4 |
| 11% | 269 | 14.9 |
| 12% | 298 | 16.5 |
* For reference, eAG in mmol/L is approximately eAG (mg/dL) divided by 18.
Why Convert?
Converting A1c to eAG can help you:
- Relate to Daily Blood Sugar Readings: eAG provides a number similar to your daily blood sugar readings, making it easier to understand your overall control.
- Set Goals: eAG can help you set realistic blood sugar targets.
- Track Progress: By monitoring your eAG alongside your A1c, you can better track the impact of your lifestyle and medication changes.
Factors Affecting A1c Results
While A1c levels generally reflect average blood sugar over 2-3 months, several factors can influence the accuracy of the test:
- Anemia: Anemia (low red blood cell count) or other blood disorders can affect A1c results.
- Hemoglobin Variants: Certain hemoglobin variants (e.g., sickle cell trait) can interfere with A1c testing.
- Kidney Disease: Advanced kidney disease can affect A1c levels.
- Pregnancy: Pregnancy can alter A1c levels due to hormonal changes and increased red blood cell turnover.
- Age: While age itself doesn’t directly affect A1c accuracy, older adults may have other health conditions that indirectly impact results.
- Ethnicity: Some studies suggest that certain ethnic groups may have slightly different relationships between A1c and average glucose levels.
If you have any of these conditions, your doctor may use other blood sugar tests or adjust your A1c target accordingly.
How to Lower Your A1c Levels
Improving your A1c levels involves a combination of lifestyle modifications and, if necessary, medication. Here are some key strategies:
- Diet:
- Focus on Whole Foods: Prioritize fruits, vegetables, whole grains, and lean proteins.
- Limit Processed Foods: Reduce your intake of sugary drinks, processed snacks, and refined carbohydrates.
- Control Portion Sizes: Be mindful of portion sizes to avoid overeating.
- Consistent Meal Timing: Eat meals and snacks at regular times to help stabilize blood sugar levels.
- Exercise:
- Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week. This could include brisk walking, jogging, cycling, or swimming.
- Strength Training: Incorporate strength training exercises to improve insulin sensitivity.
- Medication:
- Follow Your Doctor's Recommendations: Take your diabetes medication as prescribed. Do not adjust your dosage without consulting your doctor.
- Monitor Blood Sugar Levels: Regularly check your blood sugar levels to understand how your body responds to medication, diet, and exercise.
- Stress Management:
- Practice Relaxation Techniques: Engage in stress-reducing activities like yoga, meditation, or deep breathing exercises.
- Get Enough Sleep: Aim for 7-9 hours of quality sleep each night.
- Regular Monitoring:
- Consistent Testing: Regularly check your blood sugar and A1c levels as recommended by your healthcare provider.
- Keep a Record: Maintain a log of your blood sugar readings, diet, exercise, and medication. This can help you and your doctor identify patterns and make necessary adjustments to your treatment plan.
Frequency of A1c Testing
The frequency of A1c testing depends on several factors:
- Diagnosis: Newly diagnosed individuals may need more frequent testing to establish a baseline and adjust their treatment plan.
- Control: If your A1c is well-controlled (consistently within your target range), you may only need testing every 6 months.
- Treatment Changes: If your treatment plan changes (e.g., medication adjustments), you may need more frequent testing to assess the impact of the changes.
- Poor Control: If your A1c is not well-controlled, you may need testing every 3 months until you achieve your target range.

Your doctor will determine the appropriate testing frequency based on your individual needs and circumstances.
Conclusion
Understanding your A1c level and how it relates to your average blood sugar is crucial for managing diabetes and preventing complications. By knowing your A1c, converting it to eAG, and following the strategies outlined in this guide, you can take proactive steps to improve your blood sugar control and overall health. Remember to work closely with your healthcare provider to develop a personalized treatment plan that meets your specific needs. Regular monitoring, lifestyle changes, and adherence to medical advice are key to achieving and maintaining healthy A1c levels.
