The A1C Test
1. What is the A1C test?
The A1C test is a simple lab test that reflects your average blood glucose
level over the last 3 months. A small blood sample to check your A1C can be
taken at any time of the day.
2. Why should I have an A1C test?
The A1C test is the best test for you and your health care team to know how
well your treatment plan is working over time. The test shows if your blood
glucose levels have been close to normal or too high. The higher the amount of
glucose in your blood, the higher your A1C result will be. A high A1C result
will increase your chances for serious health problems.
3. What is a good A1C goal?
You and your health care team should discuss the A1C goal that is right for
you. For most people with diabetes, the A1C goal is less than 7%. An A1C higher
than 7% means that you have a greater chance of developing eye disease, kidney
disease, or nerve damage. Lowering your A1C—by any amount— can improve your
chances of staying he althy.
If your number is 7% or more, or above your goal, ask your health care team
about changing your treatment plan to bring your A1C number down.

4. If I am pregnant, what is my A1C goal?
Keeping your A1C less than 6 if you are pregnant will help ensure a healthy
baby. If possible, women should plan ahead and work to get their A1C below 6
before getting pregnant.
5. How often do I need an A1C test?
Ask for an A1C test at least twice a year. Get the test more often if your
blood glucose stays too high or if your treatment plan changes.
