Decoding Your A1C Levels: A Simple Chart and Conversion to eAG
Related reading: Worst Foods That Spike Your Blood Sugar Instantly
Understanding your A1C levels is crucial for managing diabetes and prediabetes. This article breaks down what A1C is, why it's important, provides a straightforward chart for interpreting your results, and explains how to convert your A1C to estimated average glucose (eAG). Let's dive in and make sense of these key numbers!
What is A1C and Why is it Important?
The A1C test, also known as the hemoglobin A1c or HbA1c test, provides an average measure of your blood sugar (glucose) levels over the past 2-3 months. Unlike a regular blood sugar test that captures a single point in time, A1C gives you a broader picture of your blood sugar control.
Why is this important? Consistently high blood sugar levels can lead to serious health complications, including:
- Heart disease: High glucose damages blood vessels, increasing the risk of heart attack and stroke.
- Kidney disease (nephropathy): Damage to the kidneys can lead to kidney failure.
- Nerve damage (neuropathy): High glucose can damage nerves, causing pain, numbness, and other problems.
- Eye damage (retinopathy): Damage to blood vessels in the retina can lead to vision loss and blindness.
- Foot problems: Nerve damage and poor circulation can increase the risk of foot ulcers and infections.

Regular A1C testing allows you and your doctor to monitor your blood sugar control and make necessary adjustments to your treatment plan to prevent these complications. Early detection and proactive management are key.
A Simple A1C Chart for Interpretation
Here's a simple chart to help you understand your A1C levels:
| A1C Level | Interpretation |
|---|---|
| Below 5.7% | Normal |
| 5.7% - 6.4% | Prediabetes |
| 6.5% or higher | Diabetes |
Important Considerations:
- Individual Goals: While the above chart provides a general guideline, your individual target A1C level may be different, especially if you have diabetes. Talk to your doctor to determine the best A1C goal for you. Factors like age, other health conditions, and treatment plan can influence this target.
- Variability: A1C levels are an average and don't show blood sugar fluctuations. Even with a good A1C, you could still experience periods of high and low blood sugar.
- Testing Frequency: Your doctor will determine how often you need to have your A1C tested, usually every 3-6 months.
Converting A1C to eAG (Estimated Average Glucose)
Estimated Average Glucose (eAG) provides a more familiar measure of blood sugar, expressed in mg/dL (milligrams per deciliter), the same units used in daily blood glucose monitoring. Converting A1C to eAG can help you better understand your overall blood sugar control.
Here's a table to convert your A1C to eAG:
| 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 |
*mmol/L is a different unit of measurement used in some countries.

General Rule of Thumb: For every 1% increase in A1C, your eAG increases by approximately 30 mg/dL.
Example: If your A1C is 7%, your eAG is approximately 154 mg/dL. This means your average blood sugar level over the past 2-3 months has been around 154 mg/dL.
Factors That Can Affect A1C Accuracy
While A1C is a valuable tool, it's important to be aware of factors that can affect its accuracy:
- Anemia: Certain types of anemia can falsely lower A1C levels.
- Hemoglobinopathies: Conditions like sickle cell anemia or thalassemia can affect the accuracy of A1C.
- Kidney disease: Kidney disease can falsely elevate A1C levels.
- Pregnancy: A1C levels may be slightly lower during pregnancy.
- Ethnicity: Some studies suggest that A1C levels may vary slightly among different ethnic groups.
- Recent Blood Loss: Significant blood loss, such as after surgery, can also affect the accuracy of the A1C test.
If you have any of these conditions, discuss them with your doctor. They may use other tests, such as frequent blood glucose monitoring, to get a more accurate picture of your blood sugar control.
Taking Control of Your A1C Levels
Understanding your A1C levels is the first step toward effective diabetes management. Here are some tips to help you take control:
- Follow your doctor's recommendations: Adhere to your prescribed medication schedule, diet plan, and exercise routine.
- Monitor your blood sugar regularly: Use a blood glucose meter to track your blood sugar levels and identify patterns.
- Eat a healthy diet: Focus on whole, unprocessed foods, including fruits, vegetables, whole grains, and lean protein. Limit sugary drinks, processed foods, and saturated fats.
- Exercise regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Manage stress: Stress can raise blood sugar levels. Find healthy ways to manage stress, such as meditation, yoga, or spending time in nature.
- Get enough sleep: Lack of sleep can also affect blood sugar levels. Aim for 7-8 hours of sleep per night.
- Regular Check-ups: Schedule regular appointments with your doctor and other healthcare professionals, such as a registered dietitian or certified diabetes educator.
Conclusion
Decoding your A1C levels and understanding how they relate to your eAG empowers you to take a proactive role in managing your blood sugar and preventing diabetes-related complications. By working closely with your healthcare team and making healthy lifestyle choices, you can achieve optimal blood sugar control and live a long and healthy life. Remember, knowledge is power, and understanding your A1C is a crucial step in taking control of your health.
