Decoding Your A1c Level: A Complete Chart and Conversion Guide
Understanding your A1c level is crucial if you’re managing diabetes or want to assess your risk of developing it. This comprehensive guide will break down what A1c is, how it’s measured, what different levels mean, and provide you with a helpful A1c conversion chart.
What is A1c?

The A1c test, also known as the hemoglobin A1c or HbA1c test, provides an average of your blood sugar (glucose) control over the past 2 to 3 months. Unlike a standard blood glucose test that shows your blood sugar level at a single point in time, the A1c test paints a more comprehensive picture.
Red blood cells contain hemoglobin, a protein that carries oxygen. When glucose is in your bloodstream, it binds to this hemoglobin. The higher your average blood sugar levels, the more glucose will bind to your hemoglobin. The A1c test measures the percentage of your hemoglobin that has glucose attached to it. This gives healthcare professionals a reliable measure of long-term glycemic control.
Why is A1c Important?
Regular A1c testing is essential for several reasons:

- Diagnosis of Diabetes: A1c is one of the tests used to diagnose type 2 diabetes and prediabetes.
- Monitoring Diabetes Management: For individuals already diagnosed with diabetes, A1c helps track how well their blood sugar levels are being controlled with medication, diet, and exercise.
- Predicting Long-Term Complications: Consistent elevated A1c levels increase the risk of developing long-term complications of diabetes, such as heart disease, kidney disease, nerve damage (neuropathy), and eye damage (retinopathy).
- Adjusting Treatment Plans: Based on A1c results, doctors can adjust medication dosages, dietary recommendations, and exercise routines to optimize blood sugar control.
Understanding A1c Results: Chart and Interpretation
So, what do different A1c levels mean? Here’s a general guideline:
- Normal: Below 5.7%
- Prediabetes: Between 5.7% and 6.4%
- Diabetes: 6.5% or higher
It's important to remember that these are general guidelines, and your doctor may have different targets for your specific situation, especially if you have certain health conditions.
A1c Conversion Chart: Converting A1c to eAG (Estimated Average Glucose)
The A1c percentage can be converted to an estimated average glucose (eAG), which is the average blood glucose level measured in mg/dL (milligrams per deciliter). This allows patients to relate their A1c to the numbers they see on their glucose meter.
Here's an A1c conversion chart to help you understand the relationship between A1c and eAG:
A1c (%) | Estimated Average Glucose (eAG) mg/dL | Estimated Average Glucose (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 | 11.0 |
9.0 | 212 | 11.8 |
9.5 | 226 | 12.6 |
10.0 | 240 | 13.4 |
10.5 | 255 | 14.2 |
11.0 | 269 | 15.0 |
11.5 | 283 | 15.8 |
12.0 | 298 | 16.6 |
Note: mmol/L is a different unit of measurement for glucose. This is commonly used in many countries outside of the US.
This table is a handy reference, but it’s essential to discuss your specific A1c results and their implications with your healthcare provider.
Factors That Can Affect A1c Results
While A1c is generally reliable, certain conditions and factors can affect its accuracy:
- Anemia: Can falsely lower A1c readings.
- Hemoglobinopathies: Conditions affecting hemoglobin, such as sickle cell anemia, can interfere with the test.
- Kidney Disease: Can affect the lifespan of red blood cells and alter A1c results.
- Pregnancy: Can lower A1c levels due to increased red blood cell turnover.
If you have any of these conditions, discuss with your doctor how it might affect your A1c results. They may recommend alternative blood sugar monitoring methods.
How Often Should You Get Your A1c Tested?
The frequency of A1c testing depends on individual circumstances:
- Well-Controlled Diabetes: If your blood sugar levels are consistently within the target range, your doctor may recommend A1c testing twice a year.
- Uncontrolled Diabetes or Change in Treatment: If your diabetes is not well-controlled, or if your treatment plan has recently changed, your doctor may recommend A1c testing every 3 months.
- Prediabetes: Individuals with prediabetes should have their A1c checked at least once a year, or more frequently if they have other risk factors for diabetes.
Tips for Lowering Your A1c Level
If your A1c level is elevated, there are several steps you can take to lower it:

- Follow a Healthy Diet: Focus on whole, unprocessed foods, and control portion sizes. Limit sugary drinks and processed carbohydrates.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week. Consult your doctor before starting any new exercise program.
- Take Medications as Prescribed: If your doctor has prescribed medication for diabetes, take it exactly as directed. Do not skip doses or adjust the dosage without consulting your doctor.
- Monitor Your Blood Sugar Regularly: Use a glucose meter to check your blood sugar levels regularly. This will help you understand how different foods and activities affect your blood sugar.
- Manage Stress: Chronic stress can raise blood sugar levels. Find healthy ways to manage stress, such as yoga, meditation, or spending time in nature.
- Get Enough Sleep: Lack of sleep can negatively impact blood sugar control. Aim for 7-8 hours of quality sleep per night.
- Regular checkups: Regular visits with your doctor and diabetes educator can help you stay on track with your treatment plan and make necessary adjustments.
