Follow these suggestions to help you consistently perform
good fingersticks:
Suggestion Reason
Perform a deep and rm
puncture.
An adequate puncture
is crucial to obtaining a
free-owing drop of blood.
Keep the patient’s hand below
the level of his or her heart.
This will improve the
blood ow.
Hold the capillary tube at a
slight descending angle to the
drop of blood.
This will make the capillary
tube ll faster.
Fill the capillary in less than
10 seconds.
This will ensure proper mixing
of blood and anticoagulant,
which prevents clotting.
Dispense blood from the
capillary tube in less than
ve minutes.
After ve minutes, the blood
may begin to clot in the
capillary tube.
If blood stops owing, wipe
nger rmly with gauze.
You can improve blood ow by
reopening the puncture.
WARNING: Squeezing the finger excessively may cause
inaccurate test results.
