Decoding Your A1c Levels: A Complete Guide to the A1c Chart and eAG
Understanding your A1c levels is crucial for managing diabetes or prediabetes. This guide will break down the A1c chart and estimated Average Glucose (eAG), providing you with the information you need to interpret your results and work effectively with your healthcare provider. We'll cover everything from what A1c is, to how it's measured, and what the numbers actually mean for your health.
What is A1c? A Deep Dive
The A1c test, also known as the hemoglobin A1c test, is a blood test that reflects your average blood sugar levels over the past 2 to 3 months. Unlike a daily blood glucose check, which shows your blood sugar at a specific moment in time, the A1c provides a longer-term picture of your blood sugar control. It measures the percentage of your hemoglobin – a protein in red blood cells that carries oxygen – that is coated with sugar (glycated). The higher your blood sugar levels, the more hemoglobin will be glycated.

Why is this important? High A1c levels over time indicate poor blood sugar control, which can lead to serious health complications, including heart disease, kidney disease, nerve damage (neuropathy), and vision loss (retinopathy).
How is the A1c Test Performed?
The A1c test is a simple blood test, usually performed in a doctor’s office or lab. No fasting is required, meaning you can eat and drink normally before the test. A healthcare professional will draw a blood sample, which is then sent to a lab for analysis. Results are typically available within a few days. Discuss the results with your doctor or other qualified health professionals.
The A1c Chart: Understanding the Numbers
The A1c chart provides a guideline for interpreting your A1c results. Here's a breakdown of the common A1c ranges and what they typically indicate:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
It's important to remember that these are general guidelines, and your target A1c level may be different based on your individual health circumstances and the recommendations of your healthcare provider.
Estimated Average Glucose (eAG): Relating A1c to Daily Blood Sugar
The eAG (estimated Average Glucose) translates your A1c percentage into an average blood sugar reading, expressed in mg/dL (milligrams per deciliter). This can be helpful for people who are more familiar with daily blood sugar monitoring and want to understand their A1c in a more relatable way. The formula used to convert A1c to eAG is: eAG (mg/dL) = 28.7 x A1c - 46.7. Here's an example table to illustrate the conversion:
| 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 | 13.3 |
| 11.0 | 269 | 14.9 |
| 12.0 | 298 | 16.5 |
Remember that this is just an estimate. Individual blood sugar levels can vary throughout the day due to factors like diet, exercise, stress, and medications.
Factors That Can Affect A1c Results
Several factors can influence your A1c test results, leading to falsely high or low readings. These factors can include:
- Anemia and other blood disorders: Conditions affecting red blood cells can alter the A1c result.
- Kidney disease: Kidney disease can affect the accuracy of the A1c test.
- Certain medications: Some medications, such as certain supplements, can affect A1c.
- Pregnancy: A1c levels may be lower during pregnancy.
- Ethnicity: Some studies suggest that certain ethnic groups may have slightly different relationships between A1c and average glucose levels.
It's essential to inform your doctor about any medical conditions or medications you're taking, so they can accurately interpret your A1c results.
What to Do If Your A1c is High
If your A1c level is higher than your target range, it's essential to take action to improve your blood sugar control. This may involve:
- Lifestyle Modifications: Dietary changes, regular physical activity, and weight management are key components of managing blood sugar levels. Consult with a registered dietitian or certified diabetes educator to develop a personalized meal plan.
- Medication: Your doctor may prescribe medications to help lower your blood sugar levels. It's important to take your medications as prescribed and follow your doctor's instructions carefully.
- Regular Monitoring: Frequent blood sugar monitoring can help you track your progress and make adjustments to your treatment plan as needed.
- Stress Management: Stress can significantly impact blood sugar levels. Practice relaxation techniques such as yoga, meditation, or deep breathing exercises to manage stress effectively.
- Consultation with a Healthcare Professional: Regular follow-up appointments with your doctor, certified diabetes educator, and other healthcare professionals are crucial for ongoing management of your diabetes or prediabetes.
Benefits of Achieving Target A1c Levels

Achieving and maintaining your target A1c level is essential for preventing or delaying the onset of diabetes-related complications. The benefits of good blood sugar control include:
- Reduced risk of heart disease and stroke
- Reduced risk of kidney disease
- Reduced risk of nerve damage (neuropathy)
- Reduced risk of vision loss (retinopathy)
- Improved energy levels and overall well-being
How Often Should You Get Your A1c Tested?
The frequency of A1c testing depends on your individual circumstances. Generally, the recommendations are as follows:
- People with well-controlled diabetes: At least twice a year.
- People with diabetes who are not meeting their target A1c: Every 3 months.
- People with prediabetes: Annually.
Your doctor will determine the most appropriate testing frequency for you based on your individual needs.
