We strongly recommend you do AST 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.
˙You are testing for hyperglycemia.
˙Your AST results do not correspond with the way you feel.
˙Your routine glucose results are often fluctuating.
˙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 a site that has not been rubbed exhibits a
measurably different glucose concentration than blood from the fin-
ger. When the puncture site is rubbed prior to blood extraction, the
difference is markedly reduced.
Please follow suggestions below before puncturing the skin:
˙Rub the puncture site approximately 20 seconds before penetration.
˙Use a clear cap (included in the kit) while setting the lancing device.
