Alternate Site Testing (Ast) - Accu-Chek Aviva Nano User Manual

Alternate Site Testing (AST)

You have the option of testing other places on your body besides the fingertip.
Blood obtained from a fingertip or palm can be used at any time to measure blood
glucose. The two palm testing sites are the fleshy areas under the thumb (thenar)
and under the little finger (hypothenar). If blood from an alternate site such as the
19
forearm, upper arm, thigh, or calf is used, there are certain times when testing is not
appropriate (see next page). This is because your glucose level changes quicker in
your fingertip or palm than in the alternate sites. These differences may cause you to
make the wrong therapeutic decision producing adverse health effects. Please read
the following section before you try testing from other places.
