Understanding Out‑of‑Range Control Results
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
1. Were the test strips or control solutions
expired?
2. Did you wipe the tip of the control
solution bottle before use?
3. Were the caps on the test strip
container and the control solution
bottle always closed tightly?
4. Was the test strip used immediately
after it was removed from the test strip
container?
5. Were the test strips and control
solutions stored in a cool, dry place?
6. Did you follow the directions?
7. Did you choose the correct control
solution level, either 1 or 2, when you
performed the control test?
8. 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 Chapter 4, 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.
