✅ What is A1c and Why Does it Matter?
A1c, also known as HbA1c or glycated hemoglobin, is a blood test that measures the average blood sugar levels over the past 2 to 3 months. It reflects how much glucose is attached to hemoglobin in red blood cells.
This metric helps doctors and patients understand overall diabetes control better than single-time glucose tests. The higher your blood sugar, the higher your A1c level will be.
