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 allows you to test on
the palm, the forearm, the upper arm, the calf, or the
thigh with the equivalent results to fingertip testing.
What is 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.
