Obtaining a blood drop
Use a new lancet each time you obtain blood.
This reduces the risk of infection and helps
ensure virtually pain-free blood sampling.
In general, all the
fi
ngers are suitable for obtaining
blood. Certain
fi
ngers can be unsuitable if, for example,
a skin or
fi
ngernail infection is present. We recommend
obtaining capillary blood from the side of a
fi
ngertip as
this registers the least pain (see black areas in the
illustration on the left).
The amount of blood that emerges at the puncture site
depends on the penetration depth setting and the
pressure used to hold the lancing device against the
skin.
If you
fi
nd when you perform the test that the
amount of blood is insuf
fi
cient, press the lancing
device more
fi
rmly against the skin next time. If you
still obtain insuf
fi
cient blood, also increase the
penetration depth one setting at a time when you
perform your next tests.
If, on the other hand, you obtain too much blood,
reduce the penetration depth next time.
