Do you have a sneaking suspicion that your average blood sugar levels might be a little high? If so, it's time to find out for sure. The easiest way to do this is to use a Hemoglobin (HbA1c) A1c Calculator. This calculator will help you convert your average blood sugar level into A1c percentage, so you can see where you stand. Knowing your A1c percentage is a great way to start taking steps to improve your blood sugar levels and to have your diabetes under control. Stay healthy and happy!

What is A1c, and Why is It Important to Know Your Percentage?

A1c is a measure of your average blood sugar level over the past two to three months. It's important to know your A1c percentage because it can help you and your doctor see how well your diabetes treatment plan is working. If your A1c is too high, your blood sugar levels are too high, which can lead to serious health complications like heart disease, kidney disease, nerve damage, and blindness.

How to Use a Hemoglobin (Hba1c) A1c Calculator

To use a Hemoglobin (HbA1c) A1c Calculator, all you need is your average blood sugar level. You can find this number by taking your blood sugar levels several times throughout the day and then averaging out the numbers. Once you have your average blood sugar level, simply enter it into the calculator, giving you your A1c percentage.

Normal A1c Range and A1c Level Charts

Now that you know your A1c percentage, what does it mean? The American Diabetes Association (ADA) has set these A1c targets:

  • Normal: Less than 5.7%
  • Prediabetes: 5.7% to 6.4%
  • Diabetes: 6.5% or higher

The Difference Between Estimated Average Glucose (EAG) and A1c

While A1c is a great way to get an idea of your average blood sugar level, it's not the only way. Another option is Estimated Average Glucose (EAG). EAG is a calculation that uses your A1c percentage to estimate your average blood sugar levels.

The main difference between A1c and EAG is that A1c measures your blood sugar levels over a period of two to three months and is reported in percentage %, while EAG estimates your blood sugar levels that are reported in mg/dL or mmol/L.

If you're concerned about your results, talk to your doctor. They can help you interpret your results and develop a plan to improve your diabetes management.
