Alternate Site Testing (AST)
Understanding Alternate Site Testing
Consult your health care professional before you begin using the forearm for testing. AST that should be used
with this device is the forearm only. Blood glucose test results obtained from your forearm may differ
significantly from fingertip samples.
We strongly recommend that 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.
Do NOT use AST if:
You think your blood glucose is low.
You often do not notice when your blood glucose is low.
Your AST results do not match the way you feel.
You think your blood glucose is high.
Your routine glucose results are often fluctuating.
What is AST?
Besides the fingertip, you can test the forearm.
What is the advantage of AST?
You have the option of testing other places on
your body besides the fingertip.
