11. Collecting a Fingerstick Sample

Tips for a Successful Fingerstick

Make sure that you have all the supplies needed before
you start.
 Lancet device
 Sample Transfer Tubes
 Sterile alcohol prep pad
 Gauze square or cotton ball
 Band-Aid (optional)
 Puncture resistant biohazard container (SHARPS)

Do not use fingers with tight rings, scars, calluses, or
other features that prevent getting good access to the
blood.

Thoroughly clean your hands by washing with soap and
warm water first. The warm water also helps blood
circulation. Completely dry your hands. Instead, you may
use Isopropyl alcohol wipes and then dry the area with
gauze.

For better blood flow, keep your hand below your heart.

One of the middle or index fingers on either hand is
recommended.

Gently squeeze or massage the finger to be lanced, near
the tip. Good circulation can be seen if your fingertip
changes to a pinkish shade.
