Understanding Out-of-Range Control Results
w WARNING
The control 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 Action
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Did you follow the directions? Read Chapter 4, Control Tests, and repeat the control
test.
7. Did you choose the correct control
solution level, either 1 or 2, when you
performed 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.
