how a1c test is done

The A1C test is a simple blood test that measures your average blood sugar levels over the past 2-3 months. Here’s how it’s done:

• Procedure: A healthcare professional will draw a small blood sample, usually from your arm or finger.
• Preparation: No fasting is required before the test, making it convenient.
• Frequency: It’s recommended for adults over 45, or younger if you have risk factors like obesity or a family history of diabetes.

What Does the A1C Test Measure?

The test measures the percentage of your red blood cells that have sugar-coated hemoglobin. Higher percentages indicate higher average blood sugar levels.

A1C Ranges:

• Normal: Below 5.7%
• Prediabetes: 5.7% to 6.4%
• Diabetes: 6.5% or above
