We strongly recommend you do AST in the following
intervals:
In a pre-meal or fasting state (more than 2 hours since ¾
the last meal).
Two hours or more after taking insulin. ¾
Two hours or more after exercise. ¾
Do NOT use AST if:
you think your blood glucose is low. ¾
you are unawareness of hypoglycemia. ¾
your AST results do not match the way you feel. ¾
you are testing for hyperglycemia. ¾
your routine glucose results are often uctuating. ¾
you are pregnant. ¾
How to increase the accuracy?
Stimulating blood perfusion by rubbing the puncture site
prior to blood extraction has a signicant inuence on the
glucose value obtained. Blood from the site without rubbing
exhibits a measurably different glucose concentration than
blood from the nger. When the puncture site was rubbed
prior to blood extraction, the difference was signicantly re-
duced.
Please follow suggestions below before getting a
drop of blood:
Rub the puncture site about 20 seconds before pen- ¾
etration.
Use a clear cap (included in the kit) instead while setting ¾
the lancing device.
