how is an a1c test 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.

Results are given as a percentage, with the following ranges:
