Alternative Site Testing
You can test on a variety of locations

When to use AST?
Food, medication, illness, stress and exercise can aect 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.
