Understanding A1C Tests
What is an A1C Test?
An A1C test measures the average blood glucose levels over the past two to three months. Hemoglobin A1C is a form of hemoglobin that is bound to glucose, and the test provides insight into long-term blood sugar control. This test is critical for diagnosing and managing diabetes.
The A1C percentage reflects how much glucose is attached to your red blood cells. A higher percentage indicates poor blood sugar control, while a lower percentage suggests better management.
