If you’ve ever had blood work done, you may have seen something called A1c (sometimes written as HbA1c) on your lab results. For many people, this number can feel confusing or even a little intimidating. What does it actually measure? And why do doctors talk about it so often?
A1c is one of the most important tools used to understand blood sugar levels over time. Whether you have diabetes, prediabetes, or just want to stay healthy, understanding your A1c can help you take better control of your health.
What Is A1c?
A1c is a blood test that shows your average blood sugar level over the past two to three months. Unlike a single blood sugar test, which captures just one moment in time, A1c gives a bigger picture of how your blood sugar has been behaving day to day.
Here’s how it works. Sugar in your blood attaches to hemoglobin, a protein found in red blood cells. The higher your blood sugar levels are, the more sugar sticks to these cells. Since red blood cells live for about three months, the A1c test reflects your average blood sugar during that period.
Because of this, A1c is a useful tool for tracking long-term blood sugar control.
Why A1c Matters for Your Health
A1c matters because consistently high blood sugar can damage blood vessels and nerves over time. This damage increases the risk of serious health problems, including heart disease, kidney disease, vision problems, and nerve damage.
Monitoring A1c helps doctors and patients see patterns and trends. It can show whether current treatment plans are working or if adjustments are needed. Even small improvements in A1c can lower the risk of complications and support better long-term health.
The Centers for Disease Control and Prevention explains how A1c is used to manage diabetes and assess risk: https://www.cdc.gov/diabetes/managing/managing-blood-sugar/a1c.html
What Do A1c Numbers Mean?
A1c results are reported as a percentage. This number represents how much sugar is attached to your red blood cells.
In general, A1c ranges fall into these categories:
- Below 5.7%: Normal blood sugar levels
- 5.7% to 6.4%: Prediabetes
- 6.5% or higher: Diabetes
For people already diagnosed with diabetes, target A1c goals may vary depending on age, health status, and individual circumstances. A healthcare provider can help determine what range is right for you.
How Often Should A1c Be Tested?
How often you need an A1c test depends on your health and risk factors. Many people with diabetes are tested at least twice a year, while those adjusting treatment plans may need testing more often.
People with prediabetes may be tested once a year or as recommended by their healthcare provider. For individuals without diabetes, A1c may be included as part of routine blood work, especially if risk factors are present.
Factors That Can Affect A1c Results
While A1c is a helpful tool, certain factors can influence results. Conditions that affect red blood cells, such as anemia or recent blood loss, may impact A1c accuracy. Some medications and medical conditions can also play a role.
This is one reason healthcare providers look at A1c alongside other tests and health information rather than relying on a single number.
Ways to Improve or Maintain a Healthy A1c
If your A1c is higher than recommended, there are steps you can take to improve it. Small, consistent changes often lead to meaningful results.
Helpful strategies include:
- Eating balanced meals with fewer added sugars and refined carbohydrates
- Staying physically active most days of the week
- Taking medications as prescribed
- Monitoring blood sugar if recommended
- Managing stress and getting enough sleep
Improving A1c doesn’t happen overnight, but steady progress over time can make a real difference.
A1c vs. Daily Blood Sugar Testing
A1c and daily blood sugar tests serve different purposes. Daily testing shows how blood sugar responds to meals, activity, and medication in real time. A1c, on the other hand, shows long-term trends.
Using both tools together gives a more complete picture of blood sugar control and helps guide treatment decisions.
Talking to Your Doctor About A1c
If you receive an A1c result you don’t understand, it’s important to ask questions. Your healthcare provider can explain what your number means, how it compares to past results, and whether any changes are needed.
Questions you might ask include:
- What is my target A1c and why?
- How does my A1c compare to my last test?
- What steps can I take to improve it?
Open communication helps you feel more confident and informed.
Final Thoughts
A1c is more than just a number on a lab report. It’s a powerful tool that shows how your blood sugar levels affect your health over time. Understanding what A1c is and why it matters can help you make informed choices and take an active role in your care.
Whether your goal is prevention, management, or overall wellness, paying attention to A1c can support healthier outcomes and long-term peace of mind.
