Do NOT use AST if:
You think your blood glucose is low.
If you are awareness of being 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.
How to increase the accuracy?
Stimulating blood perfusion by rubbing the puncture site prior to blood
extraction has a significant influence on the glucose value obtained.
Blood from the site without rubbing exhibits a measurably different glu -
cose concentration than blood from the finger. When the puncture site
was rubbed prior to blood extraction, the difference was significantly re-
duced.
ABOUT THIS SYSTEM
When to use AST?
Food, medication, illness, stress and exercise can affect blood glucose
levels. Capillary blood at fingertip reflects these changes faster than
capillary blood at other sites. Therefore when testing blood glucose dur-
ing or immediately after meal, physical exercise, or any other event,
take
blood sample from your finger only.
We strongly recommend you to 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.

If you would like to obtain blood from sites other than the
finger, replace the lancet device cap with the clear cap. The
clear cap for AST is an optional accessory, please contact
your local customer service.
NOTE: We suggest that before getting a drop of blood rub
the pucture site about 20 seconds before penetration.
