Use a different finger each time. Set a pattern for which
finger you stick so that you will not use some fingers more than others.
Use a different device. Some blood sugar meters need smaller drops of blood. Some blood sugar meters can
use sites other than the fingers, such as the forearm, leg, or hand.
Use a lancet with a different thickness, if possible. Some lancet devices can be set to prick your skin deeply or lightly depending on the thickness of your skin and where on your body you are getting the blood.
Do not reuse the lancet. It can get dull and cause pain. A used lancet can carry bacteria that can make you sick. Some
people reuse lancets anyway. If you do, wash your hands well each time. Keep the lancet covered with the lancet device cap. And use a new lancet each
day to reduce the chance for bacteria growth.
