Alternative Site Testing (AST)
Important: There are limitations for doing AST (Alternative Site
Testing).
* AST results should not be used for CGM calibration.
* AST results should not be used for insulin dosing calculations.
Please consult your health care profes-
sional before you do AST.
What is AST?
Alternative site testing (AST) refers to
when individuals check their blood glucose
levels using areas of the body other than
the fingertip. This system allows AST at the
palm, the forearm, the upper arm, the calf
or the thigh with results as reliable as those
obtained from fingertip testing.
What's the advantage?
Fingertips feel pain more readily because they are full of nerve end-
ings (receptors). Since nerve endings are not so condensed at other
body sites, tests performed there will be less painful.
When to use AST?
Food, medication, illness, stress and exercise can affect blood glu-
cose levels.
Capillary blood at the fingertip reflects these changes faster than
capillary blood at other sites. Therefore, when testing blood glucose
during or immediately after a meal or physical exercise, results from
AST and fingertip may be significantly different.
