STEP 1: Warm the chosen hand under warm water for a few minutes. Dry hand, then select the middle finger.


STEP 2: Gently massage the entire length of that finger to increase the temperature and improve circulation.


STEP 3: Clean the tip of the middle finger with an alcohol pad.


STEP 4: Hang the arm down and gently shake fingers for a few seconds to increase blood pools in the finger.


STEP 5: Hold the hand lower than heart level and again, gently massage the lower portion of the middle finger. Firmly grasp the lower portion of the middle finger for a few seconds to restrict return circulation.


STEP 6: Choose the site on the middle fingertip and use a skin prick lancet to prick the skin.


STEP 7: Gently massage the entire length of the pricked finger to form repeated blood drops. As each drop forms, touch the tip of the drop to a circle on the absorbent collection card. Do not smear and…

STEP 8: If you are unable to get insufficient blood from the first collection, return to step 2 using a different finger.
