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 are often fluctuating.
