Alternative Site Testing - Fora D40 Series Owner's Manual

Alternative Site Testing

IMPORTANT: There are limitations with AST (Alternative Site Testing).
Please consult your health care professional before you perform AST.
● Alternative site testing should not be used
for calibrating continuous glucose meters
(CGMs).
● Alternative site testing should not be used
for insulin dose calculations.
When to use AST?
Capillary blood at the fingertip reflects these changes faster than
capillary blood at other sites. Thus, when testing blood glucose during or
immediately after a meal, physical exercise, or any other event, take a
blood sample from your finger only.
We strongly recommend that you perform AST ONLY at the following
times:
● 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.
● You are testing for hyperglycemia.
● Your AST results do not match the way you feel.
● Your routine glucose results often fluctuate.
