ABOUT ALTERNATIVE SITE TESTING (AST)
Important: There are limitations for doing AST.
Please consult your healthcare professional before
you do AST.
What is AST?
Alternative site testing (AST) means that people use
parts of the body other than fingertips to check their
blood glucose levels. This system provides you to test
on the pam, the forearm, the upper arm, the calf, or the l
thigh with the equivalent results to fingertip testing.
What’s the advantage?
Fingertips feel pain more readily
because they are full of nerve
endings (receptors). At other
body sites, since nerve endings
were not so condensed, you will
not feel as much pain as at the
fingertip.
When to use AST?
Food, medication, illness, stress and exercise can affect
blood glucose levels. Capillary blood at fingertip reflects
these changes faster than capillary blood at other sites.
Therefore when testing blood glucose during or immedi-
ately after meal, physical exercise, or any other events,
take blood samples from your finger only.
