Understanding Your A1c Levels: A Complete Guide to the A1c Chart and eAG
Understanding your A1c levels is vital, especially if you have diabetes or are at risk. This guide will explain the A1c chart, its relation to the estimated average glucose (eAG), and how to interpret your results for better health management. We’ll dive into the specifics, helping you understand what these numbers mean for your well-being.
What is A1c?
The A1c test, also known as the hemoglobin A1c test, is a blood test that measures your average blood sugar levels over the past 2 to 3 months. Unlike a daily blood sugar test that shows your glucose level at a specific moment, the A1c test provides a broader picture of your blood sugar control over time. Hemoglobin is a protein in your red blood cells that carries oxygen. When glucose (sugar) enters your bloodstream, it binds to hemoglobin. The higher your average blood sugar levels, the more glucose binds to your hemoglobin. The A1c test measures the percentage of your hemoglobin that has glucose attached to it.
Why is A1c Important?
A1c is essential because it indicates how well your diabetes treatment plan is working. Consistent high blood sugar levels, reflected by elevated A1c levels, can lead to long-term complications such as:
- Cardiovascular disease: High glucose levels damage blood vessels.
- Kidney damage (nephropathy): Glucose buildup strains the kidneys.
- Nerve damage (neuropathy): High glucose can affect nerve function, leading to numbness, tingling, and pain.
- Eye damage (retinopathy): Damage to the blood vessels in the retina.
Monitoring your A1c levels allows you and your healthcare provider to adjust your medication, diet, or exercise regimen to better manage your blood sugar levels and reduce the risk of these complications. Therefore, routine A1c testing is crucial for effective diabetes management.

The A1c chart translates your A1c percentage into meaningful information about your average blood glucose levels. Here’s a breakdown of the general ranges:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
It's crucial to understand that these ranges may slightly vary based on individual factors and specific lab guidelines. Your doctor will consider these when interpreting your results.
Here's a more detailed A1c chart showing the corresponding average blood glucose levels:

| A1c (%) | Estimated Average Glucose (eAG) (mg/dL) | Estimated Average Glucose (eAG) (mmol/L) |
|---|---|---|
| 5% | 97 | 5.4 |
| 6% | 126 | 7.0 |
| 7% | 154 | 8.5 |
| 8% | 183 | 10.1 |
| 9% | 212 | 11.8 |
| 10% | 240 | 13.3 |
| 11% | 269 | 14.9 |
| 12% | 298 | 16.5 |
This A1c chart clearly demonstrates the correlation between A1c levels and average glucose readings, facilitating a better understanding of blood sugar management.
Estimated Average Glucose (eAG): Converting A1c to Daily Blood Sugar
The estimated average glucose (eAG) is a calculation that converts your A1c percentage into an average blood sugar level that you might see on your glucose meter. Understanding your eAG can help you better connect your A1c results to your daily blood sugar readings.
The formula to estimate your average glucose from your A1c is:
- eAG (mg/dL) = (28.7 x A1c) - 46.7
- eAG (mmol/L) = (1.59 x A1c) - 2.59

For example, if your A1c is 7%, your estimated average glucose would be:
- eAG (mg/dL) = (28.7 x 7) - 46.7 = 154.2 mg/dL (approximately 154 mg/dL as seen in the table).
- eAG (mmol/L) = (1.59 x 7) - 2.59 = 8.54 mmol/L (approximately 8.5 mmol/L as seen in the table).
By knowing this conversion, you can set realistic targets for your daily blood sugar levels and adjust your lifestyle and medication as needed.
Factors Affecting A1c Results
Several factors can influence your A1c results, making it essential to discuss them with your doctor. These factors include:
- Anemia: Conditions affecting red blood cells, like anemia, can falsely lower A1c results.
- Hemoglobin Variants: Certain genetic variations in hemoglobin can interfere with the accuracy of the A1c test.
- Kidney Disease: Advanced kidney disease can impact A1c levels.
- Pregnancy: A1c levels may be lower during pregnancy due to increased red blood cell turnover.
- Certain Medications: Some medications can also affect A1c results.
If you have any of these conditions, your doctor might recommend alternative blood sugar monitoring methods, such as frequent self-monitoring of blood glucose or fructosamine tests, to get a more accurate assessment.
How Often Should You Get Tested?
The frequency of A1c testing depends on several factors, including your type of diabetes, how well your blood sugar is controlled, and your treatment plan.
- Well-controlled diabetes: If your blood sugar is consistently well-managed, your doctor may recommend getting an A1c test twice a year.
- Changes in treatment or poorly controlled diabetes: If your treatment plan has recently changed or if your blood sugar levels are not well-controlled, you may need to get tested every three months.
- Prediabetes: If you have prediabetes, your doctor may recommend getting tested every year to monitor for progression to diabetes.
Regular testing helps you and your healthcare provider stay informed and make timely adjustments to your management plan.
Tips for Lowering Your A1c Levels
Lowering your A1c levels involves a combination of lifestyle changes and medical management. Here are some tips:
- Follow a Balanced Diet: Focus on eating whole grains, lean proteins, fruits, and vegetables. Limit processed foods, sugary drinks, and high-fat foods.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week, such as brisk walking, cycling, or swimming.
- Take Medications as Prescribed: Adhere to your prescribed medication schedule, and communicate any side effects to your doctor.
- Monitor Blood Sugar Regularly: Use a glucose meter to check your blood sugar levels regularly and track your results. This helps you understand how your diet, exercise, and medications affect your blood sugar.
- Manage Stress: High stress levels can impact blood sugar. Practice stress-reduction techniques such as meditation, yoga, or deep breathing exercises.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep per night. Lack of sleep can affect insulin sensitivity and lead to higher blood sugar levels.
By implementing these strategies, you can improve your blood sugar control and lower your A1c levels, reducing your risk of diabetes-related complications.
Conclusion
Understanding your A1c levels is crucial for effective diabetes management. The A1c chart and eAG provide valuable insights into your average blood sugar levels over time. By regularly monitoring your A1c, working closely with your healthcare provider, and making necessary lifestyle changes, you can achieve better blood sugar control and improve your overall health. Always consult with your doctor to interpret your A1c results and develop a personalized management plan tailored to your needs. Remember, knowledge is power, and understanding your A1c is a significant step toward taking control of your health.
