the test strip. Possible
causes include;
improper lancing (21g
lancet required), an air
bubble in the sample,
not allowing sample to
completely fill glass
portion of transfer
tube, or the sample
was drawn back into
the transfer tube
before removing tip
from the test strip well..
The lot of strips has
expired.

Troubleshooting
Solution
Visually confirm that no
air bubbles are in the
sample and that the
glass portion of the
transfer tube is full
before applying to test
strip.
Release pressure on
the transfer tube bulb
only after removing
transfer tube from
sample application well.
Repeat the entire
procedure (including
fingerstick) with a new
strip. If the same
message displays, use
an alternative testing
method and contact
Tech Support.
Use a different lot of
strips that has not
expired.
Verify the date setting
on the meter is current.
