AST Precautions
Do not ignore the symptoms of hyperglycemia or
•
hypoglycemia.
When the results of the test do not reflect one’s opinion, retest
•
using the fingertip test. If the test results do not reflect one’s
opinion, please consult a doctor.
Do not rely on the AST results for changing one’s treatment
•
method.
The amount glucose in alternative sites differs from person to
•
person.
Before using AST, please consult your regular physician.
•
• Helpful Tip
Results from alternative site and fingertip samples may appear
differently as there is a time lag for the glucose levels to reach
the same value. Use a fingertip for drawing 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 you palm, do not use that sample. Try puncturing
again in a smoother area.
Situations requiring fingertip test

Things to know when using AST
Please understand the following things before testing outside of the
fingertip (arms, thighs, calves).
The capillary blood of the fingertip shows the change in glucose
more rapidly than AST. 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 the glucose levels are rapidly increasing during
•
the two hours after a meal or exercise
When sick or when glucose levels seem quite lower
•
than test value
When hypoglycemia is not well recognized
•
When insulin has the biggest effect
•
2 hours after an insulin injection
•
