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
• Fasting period
• Before a meal
• Before going to bed
Situations Requiring Fingertip Test
When your blood glucose levels are unstable
• D uring two (2) hours after a meal or exercise
• W hen sick or when glucose levels seem quite lower
than test value
• W hen hypoglycemia is not well recognised
• When insulin has the biggest effect
• During two (2) hours after an insulin injection

AST Precautions
• D o not ignore the symptoms of hyperglycemia or
hypoglycemia.
• W hen the results of the test do not reflect your opinion,
retest using the fingertip test. If the fingertip result still does
not reflect the way you feel, please consult your healthcare
professional.
• D o not rely on the AST results for changing your treatment
method.
• T he amount of glucose in alternate sites differs from person
to person.
• B efore using AST, please consult your healthcare
professional.
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.
