COMPARING METER AND
LABORATORY RESULTS
The blood glucose test result you obtain
from your meter may be different from
your laboratory result due to normal
variation; however, the two results
should be within
20
% of each other.

To make an accurate comparison
between meter and laboratory results,
follow these guidelines.
Before you go to the lab:
■
Make sure your meter is clean.
■
Perform check strip and control
solution tests to make sure the meter
is working properly.
■
Comparisons will be more accurate
if you have not eaten for at least four
hours (and preferably eight hours)
prior to doing the comparative tests.
■
Take your meter with you to the lab.
While at the lab:
■
Make sure that both tests are done
within
15
minutes of each other.
■
Wash your hands before obtaining a
blood sample.
■
Never use your meter with blood that
has been placed in a gray-top test
tube.
