Alternate Site Testing (Optional)
Understanding Alternate Site Testing (AST)
Consult your healthcare professional before you begin using the forearm or palm for testing. Blood
glucose test results obtained from your forearm or palm 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 are unaware of hypoglycemia.
Your AST results do not match the way you feel.
You are testing for hyperglycemia.
Your routine glucose results are often fluctuating.
What is AST?
Besides the fingertip, you can test your
forearm or palm.
What is the advantage of AST?
You have the option of testing other places on
your body besides the fingertip.
