The Ultimate Guide to Your A1c Levels: Chart, Prediabetes Range & eAG
Understanding your A1c levels is crucial for managing your health, especially if you have diabetes or are at risk of developing it. This guide provides a comprehensive overview of A1c, including a detailed chart, information on the prediabetes range, and how A1c relates to your estimated average glucose (eAG). We'll break down the information in a clear and easy-to-understand manner, giving you the knowledge to take control of your health.
What is A1c?
The A1c test, also known as the hemoglobin A1c test, is a blood test that provides an average measure of your blood sugar levels over the past 2-3 months. Unlike a daily blood sugar check, which gives you a snapshot of your glucose level at a specific moment, A1c provides a broader picture of your blood sugar control over time.
Here's how it works: When glucose (sugar) enters your bloodstream, it attaches to hemoglobin, a protein in red blood cells that carries oxygen. The more glucose in your blood, the more hemoglobin gets glycated (coated with glucose). The A1c test measures the percentage of your hemoglobin that is glycated.

Why is A1c Important?
The A1c test is primarily used to:
- Diagnose prediabetes and diabetes: An elevated A1c level can indicate that you have prediabetes or diabetes.
- Monitor blood sugar control in people with diabetes: Regular A1c testing helps you and your doctor see how well your treatment plan is working and make adjustments as needed.
- Reduce the risk of diabetes complications: Keeping your A1c within the target range can help prevent or delay long-term health problems associated with diabetes, such as heart disease, kidney disease, nerve damage, and vision loss.
A1c Chart: Understanding Your Results
Here's a breakdown of what different A1c levels mean:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
| **A1c Level** | Interpretation | Recommended Action |
|---|---|---|
| Less than 5.7% | Normal blood sugar levels. | Maintain a healthy lifestyle through diet and exercise. Continue regular checkups. |
| 5.7% to 6.4% | **Prediabetes**. Higher risk of developing type 2 diabetes. | Implement lifestyle changes like diet modification and increased physical activity. Consult with your doctor about potential medication options. Regular monitoring is essential. |
| 6.5% or higher | **Diabetes**. | Consult with your doctor immediately for diagnosis confirmation and treatment plan development. This may involve lifestyle changes, medication, and regular monitoring of blood glucose levels. |
Prediabetes Range: What It Means and What to Do
The prediabetes range of 5.7% to 6.4% on the A1c test indicates that your blood sugar levels are higher than normal but not high enough to be diagnosed with diabetes. This is a crucial window of opportunity to take action and prevent the development of type 2 diabetes.
What can you do if you're in the prediabetes range?
- Lifestyle Changes: Implementing lifestyle changes is the cornerstone of prediabetes management. Focus on:
- Diet: Adopt a healthy eating plan that is low in processed foods, sugary drinks, and unhealthy fats. Emphasize whole grains, fruits, vegetables, and lean protein.
- Exercise: Aim for at least 150 minutes of moderate-intensity aerobic activity per week, such as brisk walking, swimming, or cycling.
- Weight Loss: Even losing a small amount of weight (5-7% of your body weight) can significantly reduce your risk of developing diabetes.
- Medical Guidance: Work closely with your healthcare provider to:
- Monitor your A1c regularly: Regular testing helps track your progress and make adjustments to your plan as needed.
- Discuss potential medications: In some cases, your doctor may recommend medication, such as metformin, to help lower your blood sugar levels.
- Get screened for diabetes complications: Prediabetes can still increase your risk of certain complications, so it's important to get screened regularly.
A1c vs. eAG: Understanding the Relationship
Estimated Average Glucose (eAG) provides an estimated average blood glucose level based on your A1c result. It's essentially a way to translate your A1c percentage into a number that's more familiar to many people—the same number they might see on their glucose meter.
The eAG is reported in milligrams per deciliter (mg/dL), which is the same unit used for daily blood glucose measurements.
How to Convert A1c to eAG:
There's a direct correlation between A1c and eAG. A simplified formula to estimate your eAG from your A1c is:

- eAG (mg/dL) = (28.7 x A1c) - 46.7
For example, if your A1c is 7%, your estimated eAG would be:
- (28.7 x 7) - 46.7 = 154.2 mg/dL
| **A1c Level** (%) | Estimated Average Glucose (eAG) (mg/dL) | Estimated Average Glucose (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 |
While the eAG provides a useful point of reference, remember that the A1c is the primary indicator for long-term blood sugar control.
Factors That Can Affect A1c Results
While A1c is generally reliable, certain factors can affect the accuracy of the test:
- Anemia: Conditions that affect red blood cells, such as anemia, can lead to falsely low A1c results.
- Hemoglobin Variants: Certain hemoglobin variants (e.g., hemoglobinopathies) can interfere with the A1c test and produce inaccurate results.
- Kidney Disease: Advanced kidney disease can affect A1c results.
- Pregnancy: A1c levels may be slightly lower during pregnancy.
- Certain Medications: Some medications can affect blood sugar levels and, consequently, A1c results.
If you have any of these conditions, talk to your doctor about alternative ways to monitor your blood sugar control.

How Often Should You Get an A1c Test?
The frequency of A1c testing depends on your individual circumstances:
- People with diagnosed Diabetes: The American Diabetes Association recommends that individuals with diagnosed diabetes get an A1c test at least two times a year if their blood sugar is consistently in target range, and quarterly (every three months) if their treatment plan has changed or if they are not meeting glycemic goals.
- People with Prediabetes: Individuals with prediabetes should get an A1c test at least once a year, or more frequently if they have other risk factors for diabetes.
- People without Diabetes or Prediabetes: Testing isn’t routinely needed, but can be part of an overall health screening based on family history or risk factors.
Taking Control of Your Health
Understanding your A1c levels, what they mean, and how they relate to your overall health is a significant step in taking control of your well-being. By following the guidelines in this article, consulting with your healthcare provider, and implementing healthy lifestyle changes, you can effectively manage your blood sugar levels and reduce your risk of developing diabetes complications. Remember, early detection and proactive management are key to living a long and healthy life. Managing your A1c levels contributes to a healthier you.
