What Is a Normal A1c Level? Understanding the A1c Chart
Understanding your A1c level is crucial for managing your health, particularly if you have diabetes or are at risk. The A1c test, also known as the hemoglobin A1c test, provides a picture of your average blood sugar levels over the past two to three months. This article will explain what a normal A1c level is, how to interpret the A1c chart, and why this test is so important.

The A1c test measures the percentage of your red blood cells that have glucose attached to them. The higher your blood sugar levels over time, the more glucose will be attached to your hemoglobin. Unlike a fasting blood sugar test that gives a snapshot of your blood sugar at a specific moment, the A1c test provides an average over a longer period, offering a more comprehensive view of blood sugar control.
The A1c Chart: Understanding the Numbers
The A1c test results are presented as a percentage. Here’s a breakdown of how to interpret the A1c chart:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
These ranges are based on guidelines from organizations like the American Diabetes Association (ADA). However, it's crucial to discuss your specific target range with your healthcare provider, as individual factors may influence the ideal target.
Why is the A1c Test Important?
The A1c test is vital for several reasons:
- Diagnosis of Diabetes and Prediabetes: It’s a standard test for diagnosing both type 1 and type 2 diabetes, as well as prediabetes.
- Monitoring Blood Sugar Control: For individuals with diabetes, the A1c test helps monitor how well their treatment plan is working. Consistent monitoring helps prevent long-term complications associated with poorly controlled blood sugar.
- Assessing Risk of Complications: Higher A1c levels are associated with an increased risk of complications such as heart disease, kidney disease, nerve damage (neuropathy), and eye damage (retinopathy).
Converting A1c to Estimated Average Glucose (eAG)
Sometimes, it's helpful to understand what your A1c percentage translates to in terms of average blood glucose levels. The estimated Average Glucose (eAG) provides this conversion, usually reported in mg/dL. Here's a simplified version; always consult your doctor or a lab for precise readings:
| A1c (%) | Estimated Average Glucose (eAG) (mg/dL) |
|---|---|
| 6% | 126 mg/dL |
| 7% | 154 mg/dL |
| 8% | 183 mg/dL |
| 9% | 212 mg/dL |
This conversion helps individuals better understand how their A1c relates to daily blood sugar readings.

Several factors can influence A1c results, making it crucial to discuss these with your healthcare provider:
- Anemia and Hemoglobin Variants: Conditions affecting red blood cells, such as anemia or certain hemoglobin variants, can falsely raise or lower A1c readings.
- Kidney Disease: Chronic kidney disease can affect A1c levels.
- Pregnancy: A1c targets during pregnancy may differ from non-pregnant individuals.
- Medications: Certain medications can impact blood sugar levels and, consequently, A1c results.
Achieving a Normal A1c Level
If your A1c level is not within the normal range, there are steps you can take to improve it:

Lifestyle Changes:
- Diet: Follow a balanced diet, focusing on whole foods, lean proteins, and complex carbohydrates. Limit processed foods, sugary drinks, and saturated fats. Consulting a registered dietitian can provide personalized dietary recommendations.
- Exercise: Engage in regular physical activity, aiming for at least 150 minutes of moderate-intensity exercise per week.
- Weight Management: If you're overweight or obese, losing even a small amount of weight can significantly improve blood sugar control.
-
Medications:
- Your doctor may prescribe medications, such as metformin, sulfonylureas, or insulin, to help lower your blood sugar levels. It's crucial to take medications as prescribed and discuss any side effects with your healthcare provider.
-
Regular Monitoring:
- Monitor your blood sugar levels regularly using a glucose meter, especially if you have diabetes. This helps you understand how different foods, activities, and medications affect your blood sugar.
-
Follow-Up with Your Healthcare Provider:
- Regular check-ups with your doctor are essential to monitor your A1c levels, adjust your treatment plan as needed, and address any concerns.
Who Should Get Tested?
The American Diabetes Association (ADA) recommends A1c testing for:
- Adults aged 45 years or older, regardless of symptoms.
- Individuals younger than 45 who are overweight or obese and have one or more additional risk factors for diabetes, such as:
- Family history of diabetes
- Physical inactivity
- High blood pressure
- Abnormal cholesterol levels
- History of gestational diabetes
- Polycystic ovary syndrome (PCOS)
- Prediabetes identified on previous testing
- Individuals with symptoms of diabetes, such as increased thirst, frequent urination, unexplained weight loss, and blurred vision.
Conclusion
Understanding your A1c level and the A1c chart is an essential step in managing your health and preventing diabetes-related complications. By maintaining a healthy lifestyle, monitoring your blood sugar levels, and working closely with your healthcare provider, you can achieve and maintain a normal A1c level, supporting your long-term well-being. Remember that a "normal" A1c can vary based on individual health factors, so personalized advice from your physician is paramount.
