important information on limitations. To ensure a reasonable comparison, follow
these guidelines.
Before you go to the lab:
•
Bring your meter, test strip 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 taking a blood sample.
•
Take 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.
