Understanding Out‑of‑range Control results
WarnIng
The control range applies only to a control result. It only indicates that the test strips and meter are working
properly. Do not use a control result to interpret blood glucose results.
If the control result is out of range, do not use the meter until you solve the problem. 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 test?
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 2, 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.
