The A1c Chart Explained: Convert Your A1c to an eAG Level
Understanding your A1c level is crucial for managing diabetes or prediabetes. This article breaks down the A1c chart, explains how to convert your A1c to an estimated average glucose (eAG) level, and provides essential information for monitoring your blood sugar. Let's dive in!

What is A1c?
The A1c test, also known as the glycated hemoglobin test, provides an average of your blood sugar levels over the past 2-3 months. Unlike a daily blood sugar test, which gives you a snapshot in time, A1c offers a broader picture of your blood sugar control. Hemoglobin is a protein in red blood cells that carries oxygen. When glucose enters the bloodstream, it attaches to hemoglobin. The higher your average blood sugar levels, the more glucose binds to hemoglobin. The A1c test measures the percentage of hemoglobin that is glycated (glucose-bound).
Why is the A1c Test Important?
The A1c test is a vital tool for:
- Diagnosing prediabetes and diabetes: It helps determine if you fall within the range indicating diabetes or are at risk.
- Monitoring diabetes management: It provides insights into how well your treatment plan is working.
- Reducing the risk of complications: Maintaining a healthy A1c level can significantly lower the risk of long-term complications associated with diabetes, such as nerve damage, kidney disease, and heart disease.
The A1c Chart: Understanding the Numbers
Here's a breakdown of typical A1c ranges and what they generally indicate:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
It's important to note that these ranges are guidelines and your healthcare provider may have specific targets for you based on your individual health situation. Regular A1c testing helps track your progress and make necessary adjustments to your treatment plan.
A1c to eAG Conversion: Making Sense of the Numbers
While A1c gives a percentage, many find it easier to understand blood sugar in terms of milligrams per deciliter (mg/dL), which is what you typically see on a glucose meter. The estimated average glucose (eAG) provides this translation. It’s a way of expressing your A1c result as if it were the average glucose level you'd see on your meter.

Here's a simple conversion: for every 1% increase in A1c, the eAG goes up by approximately 30 mg/dL. Therefore, we can create a lookup A1c eAG conversion table.

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 | 11.0 |
9.0 | 212 | 11.8 |
9.5 | 226 | 12.6 |
10.0 | 240 | 13.4 |
10.5 | 255 | 14.2 |
11.0 | 269 | 15.0 |
11.5 | 283 | 15.8 |
12.0 | 298 | 16.6 |

Factors Affecting A1c Accuracy
While the A1c test is generally accurate, certain conditions can influence the results. These include:
- Anemia: Certain types of anemia can falsely lower or raise A1c levels.
- Hemoglobin variants: Different types of hemoglobin can affect A1c results.
- Kidney disease: Kidney problems can also impact A1c accuracy.
- Pregnancy: A1c levels may be slightly lower during pregnancy.
Always inform your doctor if you have any of these conditions, as they may need to use alternative blood sugar tests to accurately monitor your diabetes management.
How Often Should You Get an A1c Test?
The frequency of A1c testing depends on your individual situation. Generally:
- If you have diabetes and your blood sugar is well-controlled: Your doctor may recommend getting tested twice a year.
- If your treatment plan has changed or your blood sugar is not well-controlled: You may need to get tested every three months.
- If you have prediabetes: Your doctor may recommend getting tested annually to monitor your risk of developing diabetes.
Tips for Maintaining a Healthy A1c Level
Maintaining a healthy A1c level involves a combination of lifestyle modifications and medical management. Key strategies include: Understanding Hyperglycemia Symptoms Causes And Treatment
- Following a healthy diet: Focus on whole foods, fruits, vegetables, and lean protein. Limit processed foods, sugary drinks, and excessive carbohydrates.
- Engaging in regular physical activity: Aim for at least 150 minutes of moderate-intensity exercise per week.
- Monitoring your blood sugar: Regularly check your blood sugar levels to understand how different foods and activities affect them.
- Taking medication as prescribed: If you are prescribed medication for diabetes, take it consistently as directed by your healthcare provider.
- Managing stress: High stress levels can impact blood sugar control. Practice stress-reducing techniques such as meditation, yoga, or deep breathing exercises.
- Working closely with your healthcare team: Regularly communicate with your doctor, certified diabetes educator, and registered dietitian to develop a personalized diabetes management plan.
The Bottom Line
Understanding the A1c chart and how to convert your A1c to an eAG level empowers you to take control of your diabetes management. By working closely with your healthcare team, making lifestyle modifications, and monitoring your blood sugar regularly, you can achieve and maintain a healthy A1c level and reduce the risk of long-term complications. Remember that proactive management and informed decisions are key to living a healthy life with diabetes.
