Decoding Your A1c Levels: A Complete Chart and Guide (eAG Explained)
Understanding your A1c levels is crucial for managing diabetes and prediabetes. This guide breaks down everything you need to know about A1c, including what it measures, how to interpret the results with a comprehensive chart, and the connection to estimated Average Glucose (eAG). Whether you're newly diagnosed or have been managing diabetes for years, this information will empower you to take control of your health.
What is A1c and Why is it Important?
The A1c test, also known as hemoglobin A1c, glycated hemoglobin, or HbA1c, provides an average picture of your blood sugar levels over the past 2-3 months. Unlike a single blood sugar reading that fluctuates with meals and activity, the A1c test reflects the percentage of your red blood cells that have glucose attached to them.
Why is this important? Chronically high blood sugar levels can lead to serious long-term complications, including:
- Heart disease
- Kidney disease
- Nerve damage (neuropathy)
- Eye damage (retinopathy)
By monitoring your A1c, you and your healthcare provider can assess how well your current treatment plan is working and make necessary adjustments to help you stay healthy.

Interpreting your A1c results is straightforward with a helpful chart. Keep in mind that individual targets may vary based on age, overall health, and other factors, so always discuss your results with your doctor.
| A1c Level | Interpretation | Action Recommended |
|---|---|---|
| Below 5.7% | Normal | Maintain healthy lifestyle habits. |
| 5.7% - 6.4% | Prediabetes | Implement lifestyle changes (diet, exercise). Discuss with your doctor about monitoring and potential interventions. |
| 6.5% or higher | Diabetes | Consult with your doctor to develop a comprehensive diabetes management plan, including medication if needed. |
| Target A1c for many adults with diabetes: Below 7% | Optimal diabetes control (general target) | Continue following your treatment plan and regularly monitor your blood sugar. |
Note: These ranges are general guidelines. Your doctor will determine the appropriate target A1c for you.
What is eAG (Estimated Average Glucose)?
eAG, or Estimated Average Glucose, is a number that gives you an idea of what your average blood glucose has been over the past few months. It's derived from your A1c result and provides a more relatable number for many people, as it's in the same units (mg/dL or mmol/L) as the glucose readings you might get from a finger-prick glucose meter.
Think of A1c as the overall grade for the semester, while eAG is like the average of all your test scores during that same period.
A1c to eAG Conversion Chart
The following chart shows the relationship between A1c and eAG. Remember, these are estimations, and individual results can vary.
| A1c (%) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|
| 6.0 | 126 | 7.0 |
| 6.5 | 140 | 7.8 |
| 7.0 | 154 | 8.6 |
| 7.5 | 169 | 9.4 |
| 8.0 | 183 | 10.2 |
| 8.5 | 197 | 10.9 |
| 9.0 | 212 | 11.8 |
| 9.5 | 226 | 12.6 |
| 10.0 | 240 | 13.4 |
Factors That Can Affect A1c Results
While the A1c test is generally accurate, certain conditions can affect the results:
- Anemia: Can falsely lower A1c readings.
- Hemoglobinopathies (e.g., sickle cell anemia): May interfere with the test.
- Kidney disease: Can impact red blood cell lifespan.
- Pregnancy: Hormonal changes can affect A1c levels.

How to Lower Your A1c Levels
If your A1c levels are higher than your target range, there are several steps you can take to lower them:
- Diet: Focus on a balanced diet rich in fruits, vegetables, and whole grains. Limit sugary drinks and processed foods. Working with a registered dietitian or certified diabetes educator (CDE) is a good idea.
- Exercise: Regular physical activity helps improve insulin sensitivity and lowers blood sugar levels. Aim for at least 150 minutes of moderate-intensity exercise per week.
- Medication: If lifestyle changes are not enough, your doctor may prescribe medication to help lower your blood sugar.
- Regular Monitoring: Check your blood sugar regularly as advised by your doctor. This provides valuable data that will help you make informed decisions about your diet, exercise, and medication.
- Stress Management: High stress levels can impact blood sugar. Find healthy ways to manage stress, such as meditation or yoga.
When to Get Your A1c Tested
The frequency of A1c testing depends on several factors, including your diabetes control, treatment plan, and overall health.
- Well-controlled diabetes: At least twice a year.
- Changes in treatment or not meeting target A1c: Every three months.
- Prediabetes: At least annually, or more frequently if advised by your doctor.
- Newly diagnosed with diabetes: More frequent monitoring to establish a baseline and assess treatment effectiveness.
The Takeaway: A1c is a Powerful Tool for Diabetes Management
Understanding your A1c levels and eAG is essential for managing your health effectively. By working closely with your healthcare provider and making informed lifestyle choices, you can achieve and maintain optimal blood sugar control and reduce your risk of diabetes-related complications.
