To obtain a sufciently large drop of blood from
alternate sites, lancing must be deeper than on
the ngertips. However, these sites are usually
less painful.
4 Choose a eshy area of the alternate site for blood
collection and wash it with warm, soapy water.
This ensures that the puncture site is clean. Allow
the skin to dry thoroughly.
5 Prime the lancing device.
6 Press the AST cap rmly against the selected
puncture site. The AST cap has a large opening
which forms the exit point for the lancet. As the
edge of this opening is raised you can feel the
position of the exit point on your skin.
