Alternative Site Testing
Important: There are limitations with AST (Alternative Site
Testing). The alternative site testing of the system can be used
in only during steady-state blood glucose conditions. Please
consult your health care professional before you perform AST.
Alternative site testing (AST) should
not be used to calibrate continuous
glucose monitoring systems (CGMs).
Results from alternative site testing
should not be used in insulin dose
calculations.
What is AST?
Alternative site testing (AST) means that
people use parts of the body other than
the ngertips to check their blood glucose
levels. This system allows you to test
on the palm, the forearm, the upper arm, the calf or the thigh with
results equivalent to ngertip testing.
What is the advantage?
Fingertips feel pain more readily because they are full of nerve end-
ings (receptors). At other body sites, since nerve endings are not so
condensed, you will not feel as much pain as on the ngertips.
