Please refer to the section of
“About AST” for available
punctured sites.
After penetration, discard the rst
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 rstly.
Since the rst drop of blood usually contains tissue uid and •
serum, which may affect the test result, it is recommended to be
discarded.
PLEASE NOTE!
