Troubleshooting Checks Action
Was the test strip exposed to open air for
a long period of time?
If yes, repeat the control test with properly
stored strips.
Was the test strip bottle capped tightly?
If no, this will humidify strips inside. Replace
the test strips.
Was the meter functioning well?
You can use the control solution to verify the
meter’s functions. (Chapter 2)
Are the control solutions expired or
contaminated?
If yes, replace with a new control solution to
check the performance of SMBG system.
Were test strips and control solutions
stored in cool, dry places?
If no, repeat the control test with properly
stored strips or control solutions.
Did you follow the testing steps properly?
Read Chapter 2 "Control Solution Testing"
and test again. Stop using the meter if you
continue to obtain the inaccurate results. If
you have questions or need assistance,
please contact your healthcare professional.
