The HbA1c blood test, also known as the A1C test, is a common blood test used to measure your average blood sugar (glucose) levels over the past 2 to 3 months. It is primarily used to:
- Diagnose prediabetes and diabetes
- Monitor blood sugar control in people with diabetes
How Does It Work?
- The test measures the percentage of hemoglobin (a protein in red blood cells) that is coated with sugar (glycated).
- Red blood cells regenerate every 3 months, so the test reflects your average blood sugar levels over that period.
A1C Results and What They Mean:
A1C Level (%) Diagnosis
Below 5.7% Normal
5.7% - 6.4% Prediabetes
6.5% or above Diabetes
Why Is It Important?
- It helps healthcare providers assess how well your diabetes management plan is working.
- For people without diabetes, it can identify prediabetes, allowing for early intervention to prevent type 2 diabetes.
Things to Note:
- The A1C test does not require fasting.
- Certain conditions (e.g., anemia, kidney disease) can affect the accuracy of the results.
