report the glucose concentration in the serum or plasma component of your
blood. However, the results may differ somewhat due to normal variation. The
meter results can be affected by factors and conditions that do not affect

Test Strips’ package
insert for typical accuracy and precision data, and for important information on
limitations.
To ensure a reasonable comparison, follow these guidelines.
Before you go to the lab:
•
Bring your meter, test strips and control solution with you.
•
Make sure your meter is clean.
•
Perform a quality control test to make sure the meter is working properly.
•
Comparisons will be more accurate if you do not eat for at least four hours
before testing. Eight hours is preferable.
At the lab:
•
Wash your hands before obtaining a blood sample.
•
Take the blood samples for a laboratory test and for your meter within 10
minutes of each other. This will ensure an accurate comparison of results.
•
Never test blood that has been placed in test tubes containing fluoride or
other anticoagulants, this will cause falsely low results.
