obtained from different sites
each time.

test strip into the device.
(4) The blood samples are
contaminated.
(e.g.
the
pricked site is not clean)
(1) The
strips
could
be
expired or malfunctioned
due to improper storage.
Please use new strips
within the expiry date.

We recommend wiping off
the first drop of blood and
using the second drop of
blood (to avoid effusion
tissue fluid).
