What is A1C?
A1C, also known as hemoglobin A1c or HbA1c, is a blood test that measures the average blood sugar level over the past 2-3 months. It is a key indicator for diagnosing and managing diabetes.
How is A1C Measured?
During an A1C test, a small amount of blood is taken and analyzed. The test measures the percentage of hemoglobin in red blood cells that is bound to glucose (sugar).
Interpretation of A1C Levels:
Normal: Less than 5.7%
Prediabetes: 5.7-6.4%
Diabetes: 6.5% or higher
