Problem
Was the test strip exposed to open air for
a long period of time?
Was the test strip vial capped tightly?
Does the meter work properly?
Is the control solution expired or conta-
minated?
Were test strips and control solution
stored in a cool and dry place?
Did you follow the testing steps prop-
erly?
Solution
Repeat the control test with properly
stored strips.
This will humidify strips inside.
Replace the test strips.
You can use the check strip to verify
the meter's functions.
Replace with new control solution
to check the performance of your glu-
cose meter.
Repeat the control test with properly
stored strips or control solutions.
Read Chapter "Control Solution
Testing" again and retest.
