Apply the blood drop to the test strip within 15 seconds
of lancing the fingertip. Applying blood after this period
of time would falsify the result, as the coagulation proc-
CAUTION
ess would already have begun.
Testing a Capillary Blood Sample
Alternatively, you can touch
the blood drop against the
side of the sample application
area (instead of applying it to
the centre from above). The
test strip draws up the blood
by capillary action.
During this process you must
hold the blood drop to the
test strip until the flashing
blood drop symbol has disap-
peared and the meter beeps
(provided the beep tone is
turned on).
