What happens during the test?
The health professional taking a sample of your blood will:
Wrap an elastic band around your upper arm. This makes the veins below the band larger so it is easier to put a needle into the vein.
Clean the needle site with alcohol.
Put the needle into the vein.
Attach a tube to the needle to fill it with blood.
Remove the band from your arm when enough blood is collected.
Put a gauze pad or cotton ball over the needle site as the needle is removed.
Put pressure on the site and then put on a bandage.
What else should you know about the test?
The test result is usually given as a percentage. The normal A1c is less than 5.7%.
The A1c test result also can be used to find your estimated average glucose, or eAG. Your eAG and A1c show the same thing in two different ways. They both help you learn more about your average blood sugar range over the past 2 to 3 months.
