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 our Diabetes Care Info-Line:
MONTREAL: (450) 686-7100
TOLL-FREE: 1 800 363-7949
Note: Result must be marked with an L1 or L2 for
the meter to verify if control result is within range. If
result has not been marked with an L1 or L2, refer to
your test strip vial label for the glucose control ranges.
If result is not within the acceptable range, an icon of the
control vial appears on the screen while the control test
result, and time and date (if set), alternate with “Err” and
“L1” or “L2”on the display. See Understanding Control
Results on page 27 for more information.
Example of an unacceptable Level 1 control result.
9. Remove test strip from meter and discard.
Note: Marking a test as “L1”or “L2” prevents the quality
control result from taking up space in the meter’s
memory. If you do not mark the test as a control, the
control result is stored in memory and included in
averages.
