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 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.
