Things to know when using AST
Please understand the following before testing at alternative
sites (forearms, palms, thighs, and calves).
The capillary whole blood of the fingertips shows changes in
glucose levels more rapidly than in alternative sites. Therefore,
the test results from the fingertip test and AST may differ. This is
because things such as lifestyle and ingested food have an effect
on glucose levels.
Acceptable situations for AST
When your blood glucose levels are stable
• Fastingperiod
• Beforeameal
• Beforesleeping

Note:
•Results from alternative site and fingertip samples may
differ from each other as there is a time lag for the glucose
levels to reach the same value. Use a fingertip for testing
ifyousufferfromhypoglycaemiaorhaveexperienced
hypoglycaemic shock or symptoms.
Note:
•If the sample drop of blood runs or spreads due to contact
with hair or with a line in your palm, do not use that sample.
Try puncturing again in a smoother area.
