Rotate the AST cap until the desired penetration
depth is level with the indicator.

To obtain a sufficiently large drop of blood from
alternate sites, lancing must be deeper than on
the fingertips. However, these sites are usually
less painful.
4
Choose a fleshy 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 firmly 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.
