The Complete Guide to the A1c Chart and What Your Level Means
Understanding your A1c level is critical for managing diabetes and prediabetes. This guide provides a comprehensive overview of the A1c chart, explaining what A1c is, how it's measured, what your A1c level means, and what actions you can take to maintain healthy blood sugar levels. Let's dive in!

What is A1c?
The A1c test, also known as the hemoglobin A1c, HbA1c, or glycohemoglobin test, provides an average measure of your blood sugar (glucose) levels over the past 2-3 months. Unlike a daily blood sugar test, which shows your glucose level at a single point in time, A1c provides a longer-term picture.
Hemoglobin is a protein inside red blood cells that carries oxygen. When glucose in your blood attaches to hemoglobin, it becomes "glycated." The more glucose in your blood, the more glycated hemoglobin you'll have. The A1c test measures the percentage of your hemoglobin that is glycated.
Why is A1c Testing Important?
The A1c test is a crucial tool for:
- Diagnosing Prediabetes and Diabetes: A high A1c level can indicate prediabetes or diabetes.
- Monitoring Diabetes Management: For individuals with diabetes, regular A1c tests help assess how well their treatment plan is working.
- Adjusting Treatment Plans: Based on A1c results, doctors can adjust medication, diet, or exercise regimens to optimize blood sugar control.
- Preventing Complications: Maintaining a healthy A1c level can significantly reduce the risk of diabetes-related complications such as heart disease, kidney disease, nerve damage, and vision problems.
Understanding the A1c Chart
The A1c chart is a table that correlates A1c percentages with estimated average glucose (eAG) levels, which are roughly equivalent to the average daily blood sugar levels. Here's a general guide:
| A1c Level (%) | Estimated Average Glucose (eAG) (mg/dL) | Category |
|---|---|---|
| Below 5.7% | Below 117 mg/dL | Normal |
| 5.7% - 6.4% | 117 - 139 mg/dL | Prediabetes |
| 6.5% or Higher | 140 mg/dL or Higher | Diabetes |
- Normal A1c: An A1c level below 5.7% indicates that your blood sugar levels are within the normal range.
- Prediabetes: An A1c level between 5.7% and 6.4% indicates prediabetes. This means your blood sugar levels are higher than normal, but not high enough to be diagnosed with diabetes. It's a crucial time to make lifestyle changes to prevent the progression to type 2 diabetes.
- Diabetes: An A1c level of 6.5% or higher indicates diabetes. This confirms that your blood sugar levels are consistently elevated, and you need medical management to control them.
Factors Affecting A1c Results
While the A1c test is generally accurate, certain factors can affect the results:
- Anemia: Individuals with certain types of anemia may have falsely lower A1c results.
- Kidney Disease: Kidney disease can interfere with the accuracy of the A1c test.
- Hemoglobin Variants: Certain hemoglobin variants (e.g., sickle cell trait) can also affect A1c results.
- Pregnancy: A1c levels may be lower during pregnancy due to increased red blood cell turnover.
- Blood Transfusions: Recent blood transfusions can temporarily affect A1c levels.

It is essential to discuss any health conditions or potential interferences with your doctor to ensure accurate interpretation of your A1c results.
What to Do Based on Your A1c Level
Here's a breakdown of actions based on your A1c category:
Normal A1c (Below 5.7%)
- Maintain a Healthy Lifestyle: Continue to eat a balanced diet, exercise regularly, and maintain a healthy weight.
- Regular Checkups: Continue with regular checkups with your doctor, and follow their advice on blood sugar monitoring if recommended.
Prediabetes (5.7% - 6.4%)
- Lifestyle Modifications: Implement significant lifestyle changes, including:
- Diet: Focus on a healthy diet low in processed foods, sugary drinks, and saturated fats. Increase your intake of fruits, vegetables, and whole grains.
- Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week.
- Weight Loss: If you are overweight or obese, losing even a small amount of weight (5-7% of your body weight) can significantly reduce your risk of developing diabetes.
- Medical Monitoring: Your doctor may recommend regular A1c testing and blood glucose monitoring to track your progress. They may also discuss medication options in some cases.
Diabetes (6.5% or Higher)
- Medical Management: Work closely with your doctor or endocrinologist to develop a comprehensive diabetes management plan. This may include:
- Medication: Taking prescribed medications, such as metformin, insulin, or other glucose-lowering agents.
- Blood Glucose Monitoring: Regularly monitoring your blood glucose levels at home to track your response to treatment.
- Diet and Exercise: Adhering to a diabetes-friendly diet and regular exercise routine.
- Education: Participating in diabetes education programs to learn more about managing your condition.
Tips for Lowering Your A1c Level
Whether you have prediabetes or diabetes, these strategies can help lower your A1c level:
- Follow a Balanced Diet: Choose nutrient-rich foods, control portion sizes, and limit processed foods, sugary drinks, and unhealthy fats.
- Engage in Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, plus strength training exercises at least twice a week.
- Monitor Your Blood Sugar: Regularly check your blood glucose levels at home, as recommended by your doctor. This helps you understand how different foods and activities affect your blood sugar.
- Take Medications as Prescribed: If you have diabetes, take your medications as directed by your doctor. Don't skip doses or change your medication regimen without consulting your healthcare provider.
- 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: Aim for 7-8 hours of sleep per night. Lack of sleep can affect your blood sugar control.
- Work with a Registered Dietitian: A registered dietitian can help you develop a personalized meal plan that meets your individual needs and preferences.
- Quit Smoking: Smoking can worsen insulin resistance and increase the risk of diabetes-related complications.
How Often Should You Get an A1c Test?
The frequency of A1c testing depends on several factors:

- Individuals with Diabetes: The American Diabetes Association (ADA) recommends that individuals with diabetes have an A1c test at least twice a year if their blood sugar levels are consistently within the target range. If your blood sugar levels are not well-controlled or your treatment plan has changed, your doctor may recommend more frequent testing (e.g., every 3 months).
- Individuals with Prediabetes: If you have prediabetes, your doctor may recommend an A1c test every 1-2 years to monitor for the progression to type 2 diabetes.
- Individuals with Normal A1c: If your A1c level is normal and you have no risk factors for diabetes, your doctor may recommend an A1c test every 3 years as part of routine health screening.
Conclusion
Understanding your A1c level is an essential step in managing your blood sugar and preventing diabetes-related complications. By following a healthy lifestyle, working closely with your healthcare team, and regularly monitoring your A1c, you can effectively control your blood sugar and improve your overall health. Use this guide as a starting point for informed conversations with your doctor about your individual A1c goals and management strategies. Remember, taking control of your health is a journey, not a destination.
