Troubleshooting Checks
4. Check if the test strip was out of the
container for a long time.
5. Check if the test strips and control
solutions were stored in a cool, dry
place.
6. Check if you followed the testing
steps.
7. Check if you chose the correct control
solution level, either 1 or 2, when you
performed the test.
Action
Repeat the control test with a new test
strip.
Repeat the control test with a properly
stored test strip or control solution.
Read Chapter 9 "Control Testing for
Consumers" and test again. If you still
have problems, call Roche.
If you chose the wrong control solution
level, you can still compare the control
result to the range printed on the test
strip container.
