What is an A1c test?

ANSWER

An A1c test is key if you have diabetes, or if you doctor thinks you might have a chance of getting it. It's a common blood test that gives information about your blood sugar.

It’s the main way to find out if someone has diabetes and how they’re managing it. You might hear it called the hemoglobin A1c, HbA1c, or glycohemoglobin test.
