What you can expect
By Mayo Clinic staffDuring the A1C test, a member of your health care team simply takes a sample of blood by inserting a needle into a vein in your arm or pricking the tip of your finger with a small, pointed lancet. The blood sample is sent to a lab for analysis. You can return to your usual activities immediately.
