what is the hba1c blood test

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.
