Decoding Your A1c Levels: A Complete Guide to the A1c Chart and Conversion
Understanding your A1c levels is crucial for managing diabetes and prediabetes. This comprehensive guide will walk you through the ins and outs of the A1c chart, how to interpret your results, and how to convert A1c values to estimated average glucose (eAG). Whether you're newly diagnosed or a seasoned pro, this article aims to equip you with the knowledge you need to take control of your health.
What is A1c and Why Does it Matter?
The A1c test, also known as the hemoglobin A1c test, measures your average blood sugar (glucose) levels over the past 2 to 3 months. It does this by measuring the percentage of your red blood cells that have glucose attached to them. The higher your blood sugar levels, the more glucose will bind to the hemoglobin in your red blood cells.
Unlike a fasting blood sugar test, which provides a snapshot of your blood glucose at a specific moment, the A1c test gives you a broader picture of your blood sugar control over time. This makes it a valuable tool for diagnosing diabetes, monitoring treatment effectiveness, and making necessary adjustments to your diabetes management plan. Maintaining optimal A1c levels is crucial for preventing long-term complications associated with diabetes, such as heart disease, kidney disease, nerve damage, and vision problems.
Understanding the A1c Chart: Target Ranges and Interpretations
The A1c chart provides a reference for interpreting your A1c results and understanding their implications for your health. The target range for A1c levels typically depends on individual factors, such as age, overall health, and the presence of other medical conditions. However, the following general guidelines apply:

- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher

| A1c Level | Interpretation | Recommended Action |
|---|---|---|
| Below 5.7% | Normal blood sugar levels. | Continue healthy lifestyle choices and routine check-ups. |
| 5.7% to 6.4% | Prediabetes. Indicates an increased risk of developing type 2 diabetes. | Implement lifestyle changes such as diet modification, regular exercise, and weight management. Consider regular monitoring and consulting with a healthcare professional. |
| 6.5% or higher | Diabetes. Indicates persistently high blood sugar levels. | Consult with a healthcare professional to develop a comprehensive diabetes management plan, which may include medication, lifestyle modifications, and regular monitoring. |
It's important to remember that these are general guidelines, and your doctor may recommend a different target A1c level based on your individual circumstances. For example, older adults or individuals with certain medical conditions may have a higher target range.
A1c Conversion to Estimated Average Glucose (eAG)
The A1c test measures the percentage of glycated hemoglobin, but many people are more familiar with blood glucose readings in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). The estimated average glucose (eAG) provides a way to convert your A1c value into a more understandable format. The eAG represents the average blood sugar level over the past 2 to 3 months, calculated from your A1c result.
The following formula can be used to convert A1c to eAG (mg/dL):
eAG (mg/dL) = (28.7 x A1c) - 46.7
Here's a conversion chart for common A1c levels and their corresponding eAG values (using HTML table for best presentation):
| 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 | 10.2 |
| 8.5 | 197 | 11.0 |
| 9.0 | 212 | 11.8 |
Knowing your eAG can help you better understand how your A1c level translates into daily blood sugar readings and make more informed decisions about your diabetes management.
Factors That Can Affect A1c Results
While the A1c test is generally accurate, certain factors can influence your results:
- Anemia: Conditions affecting red blood cell production, such as anemia, can falsely lower A1c values.
- Hemoglobin Variants: Certain hemoglobin variants, such as sickle cell trait, can interfere with the accuracy of the A1c test.
- Kidney Disease: Kidney disease can affect red blood cell lifespan, leading to inaccurate A1c results.
- Pregnancy: Pregnancy can also affect A1c levels.
- Recent Blood Loss: Recent significant blood loss, or blood transfusions.

If you have any of these conditions, your doctor may use alternative methods to assess your blood sugar control, such as frequent self-monitoring of blood glucose or continuous glucose monitoring (CGM).
Tips for Improving Your A1c Levels
If your A1c level is above the target range, there are several steps you can take to improve it:
- Follow a Healthy Diet: Focus on eating a balanced diet rich in fruits, vegetables, whole grains, and lean protein. Limit your intake of processed foods, sugary drinks, and saturated and unhealthy fats. Working with a registered dietitian or certified diabetes educator can provide personalized guidance.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, swimming, or cycling. Regular exercise helps improve insulin sensitivity and lower blood sugar levels.
- Monitor Your Blood Glucose Regularly: Self-monitoring of blood glucose allows you to track your blood sugar levels throughout the day and identify patterns and trends. This information can help you make adjustments to your diet, exercise, and medication regimen.
- Take Medications as Prescribed: If you have been prescribed medication for diabetes, it's essential to take it as directed by your doctor. Don't skip doses or adjust your medication without consulting your healthcare provider.
- Manage Stress: Stress can raise blood sugar levels. Find healthy ways to manage stress, such as through relaxation techniques, yoga, or spending time in nature.
- Get Enough Sleep: Insufficient sleep can affect insulin sensitivity and blood sugar control. Aim for 7-8 hours of quality sleep per night.
Regular communication and collaboration with your healthcare team are crucial for effectively managing your blood sugar levels and achieving your target A1c level.
Conclusion
Understanding your A1c levels and the A1c chart is vital for managing diabetes and prediabetes effectively. By knowing your A1c target range and how to convert A1c to eAG, you can gain valuable insights into your blood sugar control and make informed decisions about your health. Remember to work closely with your healthcare team to develop a personalized diabetes management plan and make necessary adjustments along the way. By following a healthy lifestyle, monitoring your blood glucose regularly, and taking medications as prescribed, you can improve your A1c levels and reduce your risk of diabetes-related complications, leading to a healthier and happier life.
