COMPARING METER AND LABORATORY RESULTS
Test results from the meter and laboratory are both expressed in
whole blood equivalent units. However, the result you obtain from
your meter may differ somewhat from your laboratory result 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 guide-
lines below.
Before going to the lab:
Perform a control solution test to make sure that the meter is working
properly.
It is best to fast for at least eight hours before doing comparison
tests.
Take your meter with you to the lab.
While staying the lab:
Make sure that the samples for both tests (the meter 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 meter with blood that has been collected in a grey-
top test tube.
Use fresh capillary blood only.
