The A1C test, also known as the hemoglobin A1C or HbA1c test, measures your average blood sugar levels over the past 2-3 months. Here’s how it works:
- Blood Sample: A small blood sample is taken, usually from your arm or finger.
- Lab Analysis: The sample is sent to a lab where it is analyzed to determine the percentage of hemoglobin that is coated with sugar (glycated hemoglobin).
- Result Interpretation: The result is given as a percentage. The higher the percentage, the higher your average blood sugar levels have been.
A1C Ranges:
A1C % Diagnosis
Below 5.7% Normal
5.7% - 6.4% Prediabetes
6.5% or above Diabetes
This test is crucial for diagnosing prediabetes and diabetes, as well as monitoring how well your diabetes is being managed over time.
