Comparing Meter and
Laboratory Results
OneTouch ® Ultra ® 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
® Ultra ® 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
® Ultra ® Meter. However, results
can differ by more than ±20% in some situations. See the OneTouch ®
Ultra ® 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 going 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.
