Alternate Site Testing (AST)
Understanding Alternate Site Testing
Consult your health care professional before you begin using the forearm for testing. 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 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.
If you are pregnant.
What is AST?
Besides the fingertip, you can test your forearm.
What is the advantage of AST?
You have the option of testing other places on
your body besides the fingertip.
