how is a1c measured

The A1C test, also known as the hemoglobin A1C or HbA1c test, measures your average blood sugar levels over the past 2 to 3 months. Here's how it works:

• Blood Sample Collection: A small blood sample is taken from your finger or arm.
• Lab Analysis: The sample is sent to a lab where it is analyzed to determine the percentage of your red blood cells that have sugar-coated hemoglobin.
• Result Interpretation: The result is given as a percentage. Higher percentages indicate higher average blood sugar levels.
