What is an A1C test?

The A1C test is also called glycated hemoglobin.

The A1C test is a common blood test used to diagnose type 1 and type 2 diabetes and to later gauge how well you're managing your diabetes. The A1C test also goes by many other names, including glycated hemoglobin, glycosylated hemoglobin, hemoglobin A1C and HbA1c.

Unlike finger sticks you can do at home, which measure your blood sugar level at a given time, the A1C test reflects your average blood sugar level for the past two to three months.

Specifically, the A1C test measures what percentage of your hemoglobin — a protein in red blood cells that carries oxygen — is coated with sugar (glycated). The higher your A1C level, the poorer your blood sugar control. And if you have previously diagnosed diabetes, the higher the A1C level, the higher your risk of diabetes complications.

A1C reflects the amount of the hemoglobin that is glycated. Hemoglobin remains glycated for the lifespan of the red blood cell, about 90-120 days. Therefore, the A1C test reflects an average blood glucose control for the past 2-3 months.
