Fingertip
Hold the Lancing Device firmly
against the side of your finger. Press
the release button. You will hear a
click, indicating that the puncture is
complete.
Sites other than fingertip
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 careful NOT to smear the
blood sample.
The volume of blood sample must be
at least 0.7 microliter ( actual size).
STEP 3. Get a Drop of Blood
Select the puncture site either in finger or in other parts
(AST). Clean the puncture site with 70% alcohol cotton
and let it air-dry.
PLEASE NOTE
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 first.
Since the first drop of blood usually contains tissue fluid and serum,
which may affect the test result, it is recommended to be discarded.
