When to use AST?
Food, medication, illness, stress and exercise can affect blood
glucose levels. Capillary blood at the ngertip reects 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 nger 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 uctuate.
