What Your A1C Chart Really Means: A Simple Guide to Estimated Average Glucose (eAG)
Understanding your health metrics can feel like deciphering a secret code. One particularly important number, especially if you’re managing diabetes, is your A1C level. But what does that A1C number actually mean? This guide will break down your A1C chart, explain its relationship to Estimated Average Glucose (eAG), and give you a clear picture of what your results mean for your health.
What is A1C and Why Does it Matter?
A1C, also known as glycated hemoglobin, is a blood test that provides an average of your blood sugar levels over the past 2-3 months. Unlike a daily finger-prick blood sugar test, which gives you a snapshot in time, the A1C offers a longer-term view. This is crucial for managing diabetes, as it helps your doctor understand how well your blood sugar has been controlled over an extended period. A stable A1C means better long-term health outcomes.

- A1C directly measures the percentage of your hemoglobin that has glucose attached to it. Higher blood sugar levels over time mean more glucose binds to hemoglobin, resulting in a higher A1C percentage.
- A1C is a cornerstone of diabetes management, used to diagnose prediabetes and diabetes, and to monitor how well a treatment plan is working.
- Regular A1C testing, as recommended by your doctor, allows for timely adjustments to medication, diet, or exercise routines.
Understanding the A1C Chart and Estimated Average Glucose (eAG)
Your A1C percentage can be converted into an Estimated Average Glucose (eAG), expressed in milligrams per deciliter (mg/dL). The eAG offers a more intuitive way to understand your A1C because it mirrors the blood sugar readings you’re used to seeing on your glucose meter. Think of it like this: your A1C is like looking at your overall trend of temperature for the last few months. Your eAG is translating this trend to show what your daily average temperature was.
Here's how the A1C and eAG correlate. Please note, this correlation is an approximation, and individual results can vary:
| A1C (%) | Estimated Average Glucose (eAG) mg/dL | Interpretation |
|---|---|---|
| 5.7 - 6.4 | 117 - 138 | Prediabetes |
| 6.5 or higher | 140 or higher | Diabetes |
| 7.0 | 154 | Target A1C for many adults with diabetes |
| 8.0 | 183 | Indicates less optimal blood sugar control |
| 9.0 | 212 | Indicates poor blood sugar control, requiring potential treatment adjustments |
Important Considerations:
- Target A1C goals can vary, depending on individual health factors, age, and other conditions. Consult your doctor to determine the most appropriate A1C goal for you.
- eAG is an estimate, and individual blood sugar levels can fluctuate throughout the day. It doesn't reflect the variability of blood sugar levels, just the average.
What Do Your A1C and eAG Numbers Mean for Your Health?
- Normal Range (A1C below 5.7%): This indicates that your blood sugar levels are within a healthy range. Continue to maintain a healthy lifestyle through diet and exercise.
- Prediabetes (A1C 5.7% to 6.4%): This means you are at higher risk of developing type 2 diabetes. Lifestyle changes, such as weight loss and increased physical activity, can help prevent the progression to diabetes. Your doctor might suggest regular A1C testing to monitor your progress.
- Diabetes (A1C 6.5% or higher): This confirms a diagnosis of diabetes. Your doctor will work with you to develop a comprehensive treatment plan, including diet, exercise, medication, and regular blood sugar monitoring.
Regardless of your A1C results, it's crucial to discuss them with your healthcare provider. They can provide personalized recommendations based on your specific health needs and circumstances.
Factors that Can Affect Your A1C Results
It's important to remember that A1C results can be influenced by factors other than just blood sugar levels. These include:

- Anemia: Certain types of anemia can falsely lower A1C results.
- Kidney Disease: Kidney disease can affect the lifespan of red blood cells, impacting A1C readings.
- Hemoglobin Variants: Certain hemoglobin variants, more common in specific ethnic groups, can interfere with A1C testing.
- Pregnancy: Pregnancy can also affect A1C levels.
Always inform your doctor of any medical conditions you have or medications you are taking, as these may influence the interpretation of your A1C test.

Managing your blood sugar and aiming for a healthy A1C level is a collaborative effort between you and your healthcare team. Here are some key steps you can take:
- Follow a Healthy Diet: Focus on whole, unprocessed foods, limiting sugary drinks and refined carbohydrates. Work with a registered dietitian for personalized meal planning.
- Engage in Regular Physical Activity: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Monitor Your Blood Sugar Regularly: Use a glucose meter to track your blood sugar levels and identify patterns. This information can help you make adjustments to your diet, exercise, or medication.
- Take Medications as Prescribed: If you are prescribed medication for diabetes, take it exactly as directed by your doctor.
- Attend Regular Checkups: See your doctor regularly for A1C testing and other necessary screenings.
Understanding your A1C chart and Estimated Average Glucose (eAG) empowers you to take control of your health and actively participate in your diabetes management plan. By working closely with your healthcare provider and making informed lifestyle choices, you can achieve optimal blood sugar control and live a healthier, more fulfilling life. Remember, knowledge is power when it comes to managing your health.
