Comparing Monitor and Laboratory Results
The meter provides you with whole blood equivalent results. The
result you obtain from your monitor may differ somewhat from your
laboratory result due to normal variation. Monitor results can be af-
fected 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 re-
sults, follow the guidelines below.
Before you go to the lab:
• Perform a control solution test to make sure that the monitor is
working properly.
• Fast for at least eight hours before doing comparison tests.
• Don't forget to take your monitor with you.
While at the lab:
Make sure that the samples for both tests (the monitor test and the
lab test) are taken and tested within 15 minutes of each other.
• Wash your hands before obtaining a blood sample.
• Never use your monitor with blood that has been collected in a
gray-top test tube.
• Use fresh capillary blood only.
You may still experience variations in the results because blood glu-
cose levels can change significantly over short periods, especially
if you have recently eaten, exercised, taken medication or experi-
enced

. For example, if you have just eaten, the blood glu-
