Alternative Site Testing (AST)
You can test on a variety of locations on your body. We recommend the upper
arm, forearm and other areas of your hand as alternative puncture sites.
Important: There are limitations with testing
on alternative sites. Please consult your
doctor or health care professional before
you perform AST.
When to use AST?
Food, medication, illness, stress and exercise can affect blood glucose
levels. Capillary blood at the fingertip reflects 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 finger 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 level is low,
• you are unaware of hypoglycemia,
• you are testing for hyperglycemia,
• your test results do not match the way you feel,
• your routine glucose results often fluctuate.
