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
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 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.
