A1c Chart: From Normal Levels to Diabetes Range (with eAG Conversion)
Understanding your A1c levels is essential for managing your blood sugar and assessing your risk for diabetes. This article provides a comprehensive A1c chart, explaining what A1c is, how it's measured, and how to interpret your results. We’ll also cover the diabetes range, normal levels, and the relationship between A1c and estimated average glucose (eAG). Let’s dive in!
What is A1c?
The A1c test, also known as hemoglobin A1c, glycated hemoglobin, or HbA1c, is a blood test that provides an average of your blood sugar (glucose) levels over the past 2-3 months. It measures the percentage of your red blood cells that have glucose attached to them. The higher your blood sugar levels, the more glucose will be attached to your hemoglobin. Therefore, A1c gives doctors a long-term view of blood sugar control, unlike a daily finger prick test which only shows glucose at that moment. Measuring A1c is a crucial diagnostic and monitoring tool for diabetes management.
Understanding the A1c Chart: Levels and Interpretation
The A1c chart helps you understand what your A1c results mean. Here's a breakdown of the different ranges and what they typically indicate:
| A1c Level | Interpretation | Recommendations |
|---|---|---|
| Below 5.7% | Normal | Maintain a healthy lifestyle, regular check-ups. |
| 5.7% - 6.4% | Prediabetes | Lifestyle changes (diet, exercise), regular monitoring. |
| 6.5% or Higher | Diabetes | Consult with a healthcare provider for diabetes management plan. |
It’s important to note that these ranges can vary slightly depending on the lab and the individual's specific circumstances. Your doctor will consider your overall health and other risk factors when interpreting your results.
A1c Levels: Normal Range Explained
A normal A1c level is generally considered to be below 5.7%. This indicates that your blood sugar levels have been consistently within a healthy range over the past few months. Maintaining normal A1c levels is crucial for preventing the long-term complications associated with diabetes, such as heart disease, kidney disease, and nerve damage. Achieving and maintaining these levels requires consistent healthy habits including proper diet and exercise.
Prediabetes Range and What It Means
An A1c level between 5.7% and 6.4% falls within the prediabetes range. This means that your blood sugar levels are higher than normal but not yet high enough to be classified as diabetes. Prediabetes is a critical warning sign, as it indicates an increased risk of developing type 2 diabetes in the future. Making lifestyle changes, such as adopting a healthy diet, engaging in regular physical activity, and losing weight (if overweight or obese), can often prevent or delay the progression to type 2 diabetes.
A1c Levels in the Diabetes Range
An A1c level of 6.5% or higher indicates diabetes. This means that your blood sugar levels have been consistently elevated over the past few months, which can lead to serious health problems if left unmanaged. It’s imperative to consult with a healthcare provider for a comprehensive diabetes management plan. This plan typically involves lifestyle modifications, medication (such as insulin or oral diabetes drugs), and regular monitoring of blood sugar levels.

The estimated average glucose (eAG) provides another way to understand your A1c results. The eAG is an estimate of what your average blood sugar levels have been on a daily basis, based on your A1c level. It is expressed in the same units (mg/dL) that you see on your blood glucose meter, making it easier to relate to daily blood sugar readings. The formula used for A1c to eAG conversion is:
eAG (mg/dL) = (28.7 x A1c) - 46.7
Here’s an A1c to eAG chart for quick reference:
| A1c (%) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|
| 6.0 | 126 | 7.0 |
| 7.0 | 154 | 8.6 |
| 8.0 | 183 | 10.1 |
| 9.0 | 212 | 11.8 |
| 10.0 | 240 | 13.4 |
| 11.0 | 269 | 14.9 |
| 12.0 | 298 | 16.5 |
Understanding the conversion between A1c and eAG can make managing diabetes more intuitive, as it connects the long-term view of A1c with the daily blood sugar readings.
Factors Affecting A1c Results
While A1c is a reliable test, certain factors can affect its accuracy. These include:
- Anemia: Conditions like iron deficiency anemia can falsely lower A1c levels.
- Hemoglobin Variants: Certain genetic variants in hemoglobin can interfere with A1c measurements.
- Kidney Disease: Chronic kidney disease can affect the lifespan of red blood cells, influencing A1c results.
- Pregnancy: Pregnancy can alter A1c levels.
It’s important to inform your doctor about any medical conditions or factors that could potentially affect your A1c results. They can take these factors into account when interpreting your test and develop an appropriate management plan.
How Often Should You Get Your A1c Tested?
The frequency of A1c testing depends on your individual circumstances:
- People with Diabetes: Typically, A1c is tested every 3-6 months to assess how well your diabetes management plan is working.
- People with Prediabetes: Testing is usually recommended every year to monitor for progression to diabetes.
- People with Normal A1c: Testing every 3 years, or as advised by your healthcare provider, is often recommended.

Your doctor will determine the appropriate testing frequency based on your risk factors, current health status, and treatment plan.
Tips for Maintaining Healthy A1c Levels
Maintaining healthy A1c levels involves adopting a holistic approach to lifestyle and diabetes management. Here are some tips:
- Follow a Healthy Diet: Focus on a balanced diet rich in fruits, vegetables, lean proteins, and whole grains. Limit your intake of sugary drinks, processed foods, and saturated fats.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week. This can include activities like brisk walking, cycling, or swimming.
- Monitor Blood Sugar Levels: Regularly check your blood sugar levels as recommended 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, take your medications as directed by your doctor. Do not skip or change your dosage without consulting with them first.
- Manage Stress: Find healthy ways to manage stress, such as practicing relaxation techniques, yoga, or meditation. Stress can affect blood sugar levels.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep per night. Lack of sleep can negatively impact blood sugar control.
- Stay Hydrated: Drink plenty of water throughout the day to stay hydrated.
Conclusion
Understanding the A1c chart and your individual A1c levels is crucial for assessing and managing your risk for diabetes. By knowing the normal range, prediabetes range, and diabetes range, you can take proactive steps to maintain healthy blood sugar levels and prevent long-term complications. Remember to consult with your healthcare provider for personalized guidance and a comprehensive management plan. Understanding the conversion between A1c and eAG further empoweres individuals in the management of diabetes. With proper lifestyle changes and medical care, you can lead a healthy and fulfilling life, regardless of your A1c level.
