Things to Know When Using AST
Please read the following before testing at alternate sites
(forearms and palms).
The capillary whole blood at the fingertips reflects changes in
glucose levels more rapidly than in alternate sites. The test results
from the fingertip testing and AST may differ due to factors such
as lifestyle and ingested food which affect glucose levels.
Acceptable Situations for AST
When your blood glucose levels are stable
• Fastingperiod
• Beforeameal

Note:
Results from alternate sites 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 if you suffer from hypoglycemia or have experienced
hypoglycemic 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.
