Understanding Control Results
If your glucose control results are within the acceptable
range, you can feel confident that your test strips and
meter are working correctly.
If one or both of your glucose control results are outside
of the acceptable range, your system may not be
working properly. Check the following:
• Did you use control solutions or test strips that
were past their expiration date?
• Did you leave the cap off the vial of test strips or
glucose control solutions?
• Did the code in the meter match the code on the
test strip vial label?
• Did you follow the testing steps exactly?
• Did you use the proper glucose control solution for
the test strips you used?
• Did you select the appropriate control result level
(L1 or L2)?
Repeat the glucose control test. If the result still is not
acceptable, contact Roche Diagnostics during business
hours.
