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.
We strongly recommend you do AST ONLY in the following intervals:
In a pre-meal or fasting state (more than 2 hours since the last meal).
Two hours or more after taking insulin.
Two hours or more after exercise.
