Troubleshooting Checks Action
Were the test strips or control
solutions expired?
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.
Did you wipe the tip of the
control solution bottle before
use?
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.
Were the caps on the test strip
container and the control
solution bottle always closed
tightly?
Replace the test strips or control solution if you think
either was uncapped for some time. Repeat the control
test.
Was the test strip used
immediately after it was
removed from the test strip
container?
Repeat the control test with a new test strip and a
fresh drop of control solution.
Were the test strips and control
solutions stored in a cool, dry
place?
Repeat the control test with a properly stored test strip
or control solution.
Did you follow the directions? Read the chapter Control Tests and repeat the control
test.
Did you choose the correct
control solution level, either 1 or
2, when you performed the 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.
Are you still unsure of the
problem?
