Fingertip
Press the lancing device’s tip firmly
against the side of your fingertip. Press
the release button to prick your finger,
then a click indicates 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 attention
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 firstly.
Since the first drop of blood usually contains tissue fluid and serum, which
may affect the test result, it is recommended to discard it.
