Decoding Your A1c Levels: A Complete Chart and Conversion Guide
Understanding your A1c levels is crucial for managing and monitoring diabetes and prediabetes. This guide provides a comprehensive overview of A1c, explaining what it is, how it's measured, what the different levels mean, and how to convert A1c to estimated average glucose (eAG). We will also explore factors that can influence your A1c readings and offer practical tips for maintaining healthy levels.
What is A1c?
The A1c test, also known as the hemoglobin A1c test or HbA1c test, is a blood test that provides an average measure of your blood sugar levels over the past 2 to 3 months. Unlike a fasting blood sugar test, which gives a snapshot of your blood glucose at a specific moment, A1c reflects longer-term glucose control. Hemoglobin is a protein in your red blood cells that carries oxygen. When glucose (sugar) in your blood attaches to hemoglobin, it forms glycated hemoglobin. The higher your average blood sugar levels, the more hemoglobin will be glycated. The A1c test measures the percentage of your hemoglobin that is glycated.
Why is A1c Important?
The A1c test is a vital tool for diagnosing prediabetes and diabetes and for monitoring how well a person with diabetes is managing their blood sugar levels. Keeping your blood sugar within the target range can help prevent or delay long-term complications of diabetes, such as:
- Heart disease
- Kidney disease (nephropathy)
- Nerve damage (neuropathy)
- Eye damage (retinopathy)
Regular A1c testing allows healthcare providers to adjust treatment plans and offer guidance on lifestyle modifications to optimize blood sugar control.
A1c Levels Chart: Understanding the Ranges
The following chart provides a general guideline for interpreting A1c levels:

| A1c Level | Category | Implications |
|---|---|---|
| Less than 5.7% | Normal | Indicates normal blood sugar levels. |
| 5.7% to 6.4% | Prediabetes | Signifies an increased risk of developing type 2 diabetes. Lifestyle changes are recommended. |
| 6.5% or higher | Diabetes | Indicates diabetes. Medical management is required. |
It's important to note that target A1c levels may vary depending on individual factors, such as age, other health conditions, and the specific type of diabetes. Your healthcare provider will determine the most appropriate target range for you.
A1c to eAG (Estimated Average Glucose) Conversion
The A1c test results are expressed as a percentage, but it can be helpful to understand what that percentage translates to in terms of average blood sugar levels. The eAG provides this conversion. Here's a conversion chart to help you understand the relationship between A1c and eAG:

| A1c (%) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|
| 6% | 126 | 7.0 |
| 7% | 154 | 8.6 |
| 8% | 183 | 10.1 |
| 9% | 212 | 11.8 |
| 10% | 240 | 13.4 |
| 11% | 269 | 14.9 |
| 12% | 298 | 16.5 |
You can also use online A1c to eAG calculators to find the corresponding eAG value for your A1c result. The formula used to calculate eAG is:
- eAG (mg/dL) = (28.7 x A1c) - 46.7
- eAG (mmol/L) = (1.59 x A1c) - 2.59
Factors Affecting A1c Accuracy
While the A1c test is generally reliable, certain factors can affect its accuracy:
- Anemia: Conditions that cause anemia can impact red blood cell turnover, potentially leading to falsely lower A1c results.
- Hemoglobin Variants: Certain hemoglobinopathies (abnormal hemoglobin) can interfere with A1c testing.
- Kidney Disease: Kidney disease can affect the lifespan of red blood cells, leading to inaccurate A1c readings.
- Pregnancy: A1c levels can be lower during pregnancy due to increased red blood cell turnover.
- Ethnicity: Some studies have shown differences in A1c levels among different ethnic groups.
If you have any of these conditions, discuss with your doctor whether A1c is the appropriate test for you and if any adjustments need to be made to interpret your results accurately.

Tips for Maintaining Healthy A1c Levels
Whether you have prediabetes or diabetes, there are several steps you can take to manage your A1c levels and improve your overall health:
- Follow a Healthy Diet: Focus on consuming whole, unprocessed foods, including plenty of fruits, vegetables, and whole grains. Limit your intake of sugary drinks, processed foods, and saturated and trans fats.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, jogging, or cycling. Incorporate strength training exercises at least twice a week.
- Monitor Your Blood Sugar Levels: Regularly check your blood sugar levels as directed by your healthcare provider. This will help you understand how your body responds to different foods and activities.
- Take Medications as Prescribed: If you have diabetes, follow your doctor's instructions carefully regarding medication dosage and timing.
- Manage Stress: Chronic stress can raise blood sugar levels. Practice stress-reducing techniques such as yoga, meditation, or deep breathing exercises.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night. Poor sleep can affect blood sugar control.
- Stay Hydrated: Drink plenty of water throughout the day.
When to See Your Doctor
It's essential to see your doctor regularly for A1c testing and to discuss your results and treatment plan. Contact your doctor sooner if you experience any of the following:
- Symptoms of high blood sugar, such as increased thirst, frequent urination, and blurred vision.
- Symptoms of low blood sugar, such as shakiness, sweating, and confusion.
- Changes in your medication or treatment plan.
- Difficulty managing your blood sugar levels.
Conclusion
Understanding your A1c levels is an important step in managing diabetes and prediabetes. By understanding what A1c is, how it relates to average blood sugar levels, and the factors that can influence your readings, you can work with your healthcare provider to develop a personalized plan for achieving optimal blood sugar control and preventing long-term complications. Remember, a healthy lifestyle, regular monitoring, and close communication with your doctor are key to living well with diabetes.
