9. Collecting a Fingerstick Sample
Tips for a Successful Fingerstick
• Make sure that you have all the supplies needed before
you start.
▪ 21g Lancet device (Single use, auto disabling)
▪ Sample Transfer Tubes
▪ Sterile alcohol prep pads
▪ Gauze square and Band-Aids
▪ Biohazard waste container (SHARPS)
• For fingerstick blood testing, increasing the flow of blood in the finger
will help you capture a good drop of blood. Before you prick the finger,
have the patient warm their hand by washing it in warm water, holding
it under their armpit, or by using a hand warmer. Ensure that the
patient’s hand is dry prior to testing.
• Do not use fingers with tight rings, scars, calluses, or other features
that prevent getting good access to the blood sample.
• 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 the patient’s fingertip changes to a pinkish
shade.
• Use a 21g 1.8 mm depth single-use auto-disabling lancet. Smaller
gauge/shallow depth lancets (i.e. diabetes 23g lancets) should not
be used. Refer to the Lancet device instructions for more information
on use.
• Lance the fleshy part of the fingertip just slightly left or right of the
center. Press lancet firmly against finger.
• For better blood flow, you may have the patient hold their hand below
their heart. If necessary, squeeze the finger from the sides to open
the wound for proper blood flow to produce a pea sized drop.
