Step Nine is puncturing the finger with the lancet.

Step Nine Video Narration:

Now that the finger is cleaned and primed, it's time to take the lancet and puncture the site. The site used should be the top of the finger, roughly halfway between the finger pad and the nail bed. Puncture the side of the finger pad in one continuous motion using a retractable lancet. The side of the finger pad is recommended and will hurt less than on top of the finger pad, since there are less nerve endings.

Rock your finger to get a drop of blood, and wipe it away with a lint-free wipe. Do this for at least 2 drops of blood before you collect your sample. The drop should be at least the size of a split pea. Doing this will give you a purer sample of blood.
