COMPARING METER AND
LABORATORY RESULTS

Meter test results and laboratory test
results are both expressed in plasma-equivalent units.
However, your meter result 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. Your OneTouch

Meter
glucose value should agree with a laboratory measurement
within ±20% most of the time under normal conditions. A
result within that range is considered accurate when testing
with the OneTouch
®
UltraSmart
®
Meter. However, results can
differ by more than ±20% in some situations. See the
OneTouch

Test Strip package insert for typical accuracy
and precision data and for important information on
“Limitations of Procedure.”
To make an accurate comparison between meter and
laboratory results, follow these guidelines:
Before you go to the lab:
Perform a control solution test to make sure 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.
