6 Pull back the tensioning device until you hear it click into
place.
If it does not engage, the lancing device may have uninten-
tionally already been tensioned when inserting the needle
lancet and could already be engaged.
7 The lancing device can now be used to take the blood sam-
ple.
Ensure that the blood remains in a droplet form and is not
smeared.
Blood sample from the fingertip
Place the lancing device firmly against the finger, slightly to
the side of the centre of the fingertip. Press the release but-
ton.
Lift the lancing device from the finger. You need a round
blood drop of at least 0.6 microlitres to form (corresponds to
approx. 1.4 mm, original size: ).
Blood sample from an alternative site (AST)
Choose a site that is soft, not next to a bone, with no visible
veins and without excessive body hair. Warm the puncture
site to ensure good circulation, for example by lightly mas-
saging
the area. Place and hold the lancing device against the
puncture site for a few seconds and press the release button.
Continue to hold the lancing device against your skin until a
round droplet of blood has formed under the cap. Keep ap-
plying pressure until the size of the blood drop is at least 0.6
microlitres (corresponds to approx. 1.4 mm, original size: ).
Lift the lancing device carefully away from the skin.
8 If insufficient blood was collected, increase the puncture
depth and repeat steps 5 to 7.
9 Untwist the cap and carefully remove it from the lancing
device.
