About A1C Testing

The A1C test (also known as HbA1c, glycated haemoglobin or glycosylated haemoglobin) measures the percentage of haemoglobin proteins in your blood that are coated with glucose. This provides information about your average blood glucose levels over the past 2-3 months.

Understanding A1C Values
  • Below 5.7%: Normal (non-diabetic) range
  • 5.7% to 6.4%: Prediabetes range
  • 6.5% or higher: Diabetes range
  • Target for most people with diabetes: Below 7.0%
A1C to eAG Conversion

The estimated Average Glucose (eAG) helps translate A1C values into the same units used for daily blood glucose monitoring. This makes it easier to compare A1C results with daily glucose measurements.

  • A1C 6.0% ≈ eAG 126 mg/dL (7.0 mmol/L)
  • A1C 7.0% ≈ eAG 154 mg/dL (8.6 mmol/L)
  • A1C 8.0% ≈ eAG 183 mg/dL (10.2 mmol/L)
  • A1C 9.0% ≈ eAG 212 mg/dL (11.8 mmol/L)
Important Notes
  • The relationship between A1C and average glucose can vary between individuals.
  • Certain conditions can affect A1C results, including anaemia, haemoglobin variants, and recent blood loss.
  • A1C tests should be performed in a laboratory using NGSP-certified methods for accurate results.
  • Always consult with healthcare providers about your A1C targets and results.

Understanding the A1C Calculator

The A1C Calculator is a helpful tool for people who want to know their average blood glucose levels. It takes your A1C percentage and converts it into an estimated Average Glucose (eAG) value, making it easier to understand your Diabetes management. This calculator is useful for anyone monitoring their blood sugar levels.

How A1C and eAG Relate

The A1C test shows how well blood sugar has been controlled over the last two to three months. It measures the percentage of glucose attached to hemoglobin in the blood. By converting A1C to eAG, you can see how your test results compare to daily glucose readings. Here’s what you need to know:

  • A1C 6.0% is about eAG 126 mg/dL (7.0 mmol/L).
  • A1C 7.0% is about eAG 154 mg/dL (8.6 mmol/L).
  • A1C 8.0% is about eAG 183 mg/dL (10.2 mmol/L).

Why Use the A1C Calculator?

This calculator makes managing diabetes easier by providing a quick way to see how A1C levels translate to glucose readings. Knowing these values can help you understand your overall Health and make better decisions about your diet and treatment. It’s especially beneficial during routine checkups or when adjusting medications.

Features of the A1C Calculator

The A1C Calculator offers a range of features for users. You can choose to convert from A1C to eAG or the Other way round. It also allows you to set the number of decimal places for your results and opt to see glucose values in both mg/dL and mmol/L. All of this makes the calculator flexible and user-friendly.

A1C and the Risk of Diabetes

Your A1C value can indicate your risk level for diabetes. Here are the ranges to be aware of:

  • Normal: A1C below 5.7%
  • Prediabetes: A1C between 5.7% and 6.4%
  • Diabetes: A1C 6.5% or higher

Using Your Results Wisely

Once you get your results from the A1C Calculator, it’s important to use them wisely. Always consult with your healthcare provider to discuss what your numbers mean and how you can improve them if needed. They can provide personalised advice based on your health profile.

The Science Behind A1C Testing

The A1C test is more than just a number; it reflects how well your body is managing blood sugar. It’s vital for anyone diagnosed with diabetes. Understanding what the A1C and eAG values mean can help you take control of your health and prevent complications related to diabetes.

More Information on A1C Testing

For those interested in learning more, remember that factors like your diet, exercise, and medications can all influence your A1C results. Always stay informed and proactive about your health. Regular testing and using tools like the A1C Calculator can help you stay on track.
