If your doctor has told you your A1C or you’ve seen it in your lab work, you might wonder what it is, what the number means, and how A1C is calculated.
Hemoglobin A1C is a simple blood test that measures your average blood sugar levels over the past 2-3 months.
A1C is one of the diagnostic tests used to diagnose prediabetes and diabetes.
Testing your hemoglobin A1C can give your doctor and care team important information to modify your treatment plan and help you avoid complications of uncontrolled high blood sugars.
A1C is often used along with other labs like your fasting blood glucose (FBG) and postprandial (post-meal) blood sugars for a big picture of what your blood sugars are doing.
