Please refer to the section of
“About AST” for available
punctured sites.
After penetration, discard the first
drop of blood with a clean tissue
paper or cotton. Then gently
squeeze the punctured area to
obtain blood. But be attention
NOT to smear the blood sam-
ple.
The volume of blood sample
must be at least 0.7 microliter
( actual size).
Choose a different spot each time you test. Repeated punctures in
•
the same spot may cause soreness and calluses.
Before you decide to do AST, please consult your health
•
professional firstly.
Since the first drop of blood usually contains tissue fluid and
•
serum, which may affect the test result, it is recommended to be
discarded.
PLEASE NOTE!
