There are limitations with AST (Alternative Site Testing).
Please consult your health care professional before you perform AST.
When to use AST?
Food, medication, illness, stress and exercise can affect blood glucose levels.
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.
