AST Precautions
• Before using AST, please consult your healthcare
professional.
• Do not use AST for your blood
β
-ketone test.
• Do not ignore the symptoms of hyperglycemia or
hypoglycemia.
• When 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.
• Do not rely on the AST results for changing your treatment
method.
• The amount of glucose in alternative sites differs from
person to person.
Note:
• Results from alternative 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.
• 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.
Things to Know When Using AST
Please read the following before testing at alternative sites
(forearms and palms).
The capillary whole blood of the fingertips reflects changes in
glucose levels more rapidly than in alternative 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
• During two (2) hours after a meal or exercise
• When sick or when glucose levels seem quite lower
than test value
• When hypoglycemia is not well recognised
• When insulin has the biggest effect
• During two (2) hours after an insulin injection
