Checking your meter
Are the test strip guide and measurement window clean?

Has the control solution been open for less than 3 months?

period.
yes
Have you read the section “Treating the control solutions properly” in the package insert for
the control solution?
yes
Did you follow the storage conditions for the meter, the test strips and the control solutions.
(See chapter “Test and storage conditions” and the package inserts)?
yes
Are the test strips or the control solution past their use by date?
The use by date is printed next to the
e
symbol on the label of the test strip container or on
the label of the bottle next to the
E
symbol. If the use by date of the test strips has elapsed, the
meter also displays the

no
W
If a control test produces results that are outside the specified concentration range, it is no longer
certain that the meter and test strips are functioning properly. Blood glucose tests may then produce
incorrect results.
Incorrect blood glucose results can cause the wrong therapy recommendation to be made and so
produce serious adverse health effects.
