Prior to testing, make sure the patient‘s hand is warm and relaxed before
collecting the capillary blood specimen. Use warm water to increase blood
flow if necessary. Massage the hand from the wrist up to the fingertip a few
times to encourage blood flow.
Clean the testing site with an alcohol swab or by washing hands with warm
soapy water and then dry the testing site thoroughly.
Hold the lancing device against the side of the finger to be lanced with the
cover resting on the finger. Push the release button to prick the fingertip. A
click should be heard as the lancing device activates. Gently massage from
the base of the finger to the tip of the finger to obtain the required blood
volume. Avoid smearing the drop of blood. For the greatest reduction in
pain, lance the sides of the fingertips. Rotation of sites is recommended.
Repeated punctures in the same spot can make the fingers sore and
callused.
