What Do Your A1c Levels Really Mean? A Complete Guide to the A1c Chart
Understanding your A1c levels is crucial, especially if you have diabetes or are at risk of developing it. The A1c test provides a snapshot of your average blood sugar levels over the past 2-3 months. This guide will break down what your A1c results mean, how the A1c chart works, and what you can do to manage your levels.

What is the A1c Test?
The A1c test, also known as the hemoglobin A1c test, is a blood test that measures the percentage of your red blood cells that have glucose attached to them. Glucose comes from the foods you eat, and when it builds up in your blood, it binds to hemoglobin, the protein in red blood cells that carries oxygen. The higher your blood sugar levels, the more glucose attaches to your hemoglobin.
Unlike a fasting blood sugar test, which shows your blood sugar at a specific point in time, the A1c test gives an average picture over several months, reflecting how well your blood sugar has been controlled over time.
The Importance of A1c Levels
Monitoring your A1c levels is vital for several reasons:
- Diagnosis of Diabetes and Prediabetes: The A1c test is used to diagnose both type 2 diabetes and prediabetes.
- Management of Diabetes: For individuals with diabetes, the A1c test helps monitor how well their treatment plan is working. Regular monitoring allows for adjustments in medication, diet, and exercise as needed.
- Reducing Complications: Keeping your A1c levels within the target range significantly reduces the risk of long-term diabetes complications such as nerve damage (neuropathy), kidney disease (nephropathy), eye damage (retinopathy), and cardiovascular disease.
Understanding the A1c Chart
The A1c chart translates your A1c percentage into an estimated average glucose (eAG) level, which is similar to what you would see on a daily glucose meter. Understanding the correlation between the A1c percentage and the eAG helps you better interpret your results and their implications.
Here's a breakdown of the common A1c chart ranges and their meanings:
| A1c Level (%) | eAG (mg/dL) | Interpretation |
|---|---|---|
| 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 |
Note: eAG stands for estimated Average Glucose.
Target A1c Levels
While the general guidelines for A1c levels are as shown in the chart above, it's essential to understand that target A1c levels can vary depending on individual circumstances. The American Diabetes Association (ADA) generally recommends a target A1c of less than 7% for many adults with diabetes. However, the target A1c may be different based on:
- Age: Older adults may have different targets.
- Overall Health: People with other health conditions may require different targets.
- Risk of Hypoglycemia: Individuals prone to low blood sugar (hypoglycemia) may have a higher target.
- Duration of Diabetes: Those newly diagnosed may aim for stricter control initially.
It is crucial to consult with your healthcare provider to determine the most appropriate target A1c level for you.
Factors Affecting A1c Results
It's important to recognize that several factors besides blood sugar levels can influence A1c results, leading to potentially inaccurate readings:
- Anemia: Conditions like anemia can affect hemoglobin levels, potentially skewing A1c results.
- Hemoglobin Variants: Certain hemoglobin variants, common in some ethnic groups, can interfere with A1c testing.
- Kidney Disease: Chronic kidney disease can alter red blood cell lifespan, affecting A1c accuracy.
- Pregnancy: A1c levels may be lower in pregnant women.
- Medications: Certain medications can impact A1c results.

If you have any of these conditions, discuss them with your healthcare provider to determine if alternative blood sugar monitoring methods are more appropriate.
Managing Your A1c Levels
Regardless of whether you're aiming to prevent diabetes, manage prediabetes, or control existing diabetes, the following strategies can help lower your A1c levels:
- Dietary Changes:
- Reduce Carbohydrate Intake: Focus on complex carbohydrates like whole grains, fruits, and vegetables. Limit processed foods, sugary drinks, and refined grains.
- Control Portion Sizes: Be mindful of how much you're eating at each meal.
- Choose Healthy Fats: Incorporate sources like avocados, nuts, and olive oil.
- Regular Exercise:
- Aim for 30 minutes of Moderate Exercise Most Days: Activities like brisk walking, swimming, or cycling can significantly lower blood sugar levels.
- Include Strength Training: Incorporating strength training exercises a few times a week can improve insulin sensitivity.
- Medication Management:
- Follow Your Doctor's Instructions: If you have been prescribed medication, take it exactly as directed.
- Monitor Your Blood Sugar: Regularly checking your blood sugar can help you understand how your body responds to food, exercise, and medication.
- Stress Management:
- Practice Relaxation Techniques: High stress levels can raise blood sugar. Techniques like meditation, yoga, and deep breathing can help.
- Ensure Adequate Sleep: Lack of sleep can also impact blood sugar control. Aim for 7-8 hours of quality sleep each night.
- Regular Monitoring:
- Follow your Doctor's Recommendations: Get regular A1c tests and other check-ups as recommended by your healthcare provider.
- Track Your Progress: Keep a record of your blood sugar levels, diet, exercise, and medications. This information can help you and your healthcare team make informed decisions about your treatment plan.
