w WARNING
The control solution ranges are printed on the test strip container label. If the control result is out of
range, check this list to help solve the problem.
Troubleshooting Checks
Were the test strips or control solutions expired?
Did you wipe the tip of the control solution bottle
before use?
Were the caps on the test strip container and the
control solution bottle always closed tightly?
Was the test strip used immediately after it was
removed from the test strip container?
Were the test strips and control solutions stored
in a cool, dry place?
Did you follow the directions?
Did you choose the correct control solution level,
either 1 or 2, when you performed the control
test?
Are you still unsure of the problem?

Action
Discard the test strips or control solution if either
is past the use by date. If the control solution was
opened more than 3 months ago, discard it.
Repeat the control test with an unexpired test
strip and an unexpired control solution.
Wipe the tip of the bottle with a tissue. Repeat the
control test with a new test strip and a fresh drop
of control solution.
Replace the test strips or control solution if you
think either was uncapped for some time. Repeat
the control test.
Repeat the control test with a new test strip and a
fresh drop of control solution.
Repeat the control test with a properly stored test
strip or control solution.
Read the chapter Control Tests and repeat the
control test.
If you chose the wrong control solution level, you
can still compare the control result to the range
printed on the test strip container.
