A1c Chart Explained: Convert Your A1c to an Average Blood Sugar Level
Understanding your A1c is crucial for managing diabetes and prediabetes. This article will explain what an A1c test is, how to interpret its results using an A1c chart, and how to convert your A1c level to an estimated average blood sugar (eAG) level. We will delve into the importance of monitoring your blood sugar and what steps you can take to maintain healthy levels.
What is the A1c Test?
The A1c test, also known as the hemoglobin A1c test, provides an average measure of your blood sugar (glucose) levels over the past 2-3 months. Unlike a daily blood sugar check that gives you a snapshot in time, the A1c offers a broader picture of your glucose control. This test measures the percentage of your red blood cells that have glucose attached to them. The higher your blood sugar levels have been, the more glucose will be attached to your hemoglobin, resulting in a higher A1c percentage.
Why is the A1c Test Important?
Regular A1c testing is vital for several reasons:

- Diagnosis: It's used to diagnose type 2 diabetes and prediabetes.
- Monitoring: For individuals already diagnosed with diabetes, it helps monitor how well their treatment plan is working.
- Risk Assessment: It helps assess the risk of developing long-term complications associated with diabetes, such as nerve damage, kidney disease, and vision problems.
- Personalized Management: Results allow healthcare providers to personalize treatment plans and make necessary adjustments.
Understanding the A1c Chart and Target Levels

The A1c chart is a valuable tool that helps you understand what your A1c result means in terms of your average blood sugar levels. Different A1c levels correspond to different blood glucose averages.
Here are the general A1c target ranges recommended by the American Diabetes Association (ADA):
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
It's important to note that target A1c levels may vary depending on individual factors such as age, other health conditions, and treatment plan. Always consult your healthcare provider to determine your personalized target.
Converting A1c to Estimated Average Glucose (eAG)
The A1c percentage can be converted to an estimated average glucose (eAG), which is expressed in mg/dL (milligrams per deciliter) or mmol/L (millimoles per liter). This conversion helps individuals relate their A1c result to the blood sugar levels they monitor daily. The following table demonstrates the conversion:
| A1c (%) | Estimated Average Glucose (eAG) (mg/dL) | Estimated Average Glucose (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 | 10.9 |
| 9.0 | 212 | 11.8 |
Note: This is a simplified conversion table. Consult with your doctor or use an online A1c to eAG converter for more precise estimates.

Factors Affecting A1c Results
Several factors can affect the accuracy of A1c results, including:
- Anemia: Certain types of anemia can lead to falsely low or high A1c readings.
- Hemoglobinopathies: Conditions like sickle cell anemia can interfere with the test.
- Kidney Disease: Kidney disease can affect red blood cell turnover and alter A1c levels.
- Pregnancy: Pregnancy can affect A1c readings, so specific guidelines may apply.
- Certain Medications: Some medications can interfere with the A1c test.
Always inform your healthcare provider about any medical conditions or medications you are taking.
Steps to Improve Your A1c Levels
If your A1c level is above your target range, several lifestyle changes and medical interventions can help improve it:
- Dietary Changes: Focus on a balanced diet rich in fruits, vegetables, whole grains, and lean protein. Limit your intake of sugary drinks, processed foods, and saturated fats.
- Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week.
- Weight Management: Losing even a small amount of weight can significantly improve blood sugar control.
- Medication Adherence: Take your prescribed medications as directed by your healthcare provider.
- Regular Monitoring: Monitor your blood sugar levels regularly and work with your healthcare team to adjust your treatment plan as needed.
The Importance of Regular Monitoring and Follow-Up
Regular A1c tests are a key part of diabetes management. Your healthcare provider will recommend how often you should get tested, typically every 3-6 months. Follow-up appointments are also crucial to discuss your results, adjust your treatment plan, and address any concerns you may have. Proactive management and open communication with your healthcare team are essential for achieving and maintaining optimal blood sugar control and reducing the risk of complications associated with diabetes. By using the A1c chart and understanding the conversion to average glucose levels, you can empower yourself to better manage your health.
