Troubleshooting.Checks Action
1. Are the test strips or control solution past the
“Use By” date or discard date?
If either is past the “Use By” date or discard date,
throw it away.
2. Did you wipe the tip of the control solution
bottle with a tissue prior to 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 test strip container and control
solution bottle always closed tightly?
If you think either may have been uncapped for some
time, replace the test strips or control solution.
4. Was the test strip used immediately after
removing it from the container?
Repeat the control test with a new test strip.
5. Were the test strips and control solution stored
in a cool, dry place?
Repeat the control test with properly stored test strips
or control solution.
