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.
