Comparing Meter and Laboratory Results
The test result you obtain from your meter may differ
somewhat from your laboratory results due to normal
variation. Meter results can be affected by factors and
conditions that do not affect laboratory results in the same
way. (See test strip package insert for typical accuracy and
precision data and for important information on limitations.)
To make an accurate comparison between meter and
laboratory results, follow the guidelines below.
Before you go to the lab:
•Performacontrolsolutiontesttomakesurethatthe
