Comparing Meter and Laboratory Results
The meter provides you with plasma blood equivalent results. The
result you obtain from your meter may differ somewhat from your labo-
ratory result due to normal variation. Meter results may be affected by
factors and conditions that do not affect laboratory results in the
same way. To make an accurate comparison between meter and
laboratory results, follow the guidelines below
Before going to the lab:
• Perform a control solution test to make sure that the meter is
working properly.
• Fast for at least eight hours before doing comparison tests,
if possible.
• Take your meter with you to the lab.
While staying at the lab:
Make sure that the samples for both tests 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
gray-top test tube.
• Use fresh capillary blood only.
