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 palm, the forearm, the upper arm,
the calf, or the 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 immediately after meal, physical exercise, or any other event, take blood
sample from your finger only.
