Alternative Site Testing
You can test on a variety of locations on your body.
Important
:
There are limitations with AST
(Alternative Site Testing).
Please consult your 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 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 fluctuate.
