Testing blood glucose
5
Ensure that the measurement optics cover (see pages 10 and 11)
is firmly and properly attached to the meter when you turn it on.
A cover that is not properly attached can lead to incorrect results.
Incorrect results can cause the wrong therapeutic decision to be
taken and so lead to serious adverse health effects.
If the code number displayed does not match the code number
on the test strip container, do not test blood glucose. Improper
coding leads to incorrect results. Incorrect results can cause the
wrong therapeutic decision to be taken and so lead to serious
adverse health effects.
If exp appears in the test strip symbol ( ), the test strip
you are using is past its expiry date. Check the expiry date on the
label of the test strip container. You will find it next to the
sym-
bol. Check also that the meter is set to the current date and that
the code chip that is inserted is the one that came with the test
strips you are using.
Do not test blood glucose with test strips that have expired.
Expired test strips can produce incorrect results. Incorrect results
can cause the wrong therapeutic decision to be taken and so
lead to serious adverse health effects.
Use test strips that have not expired with the code chip that
came with them.
