Comparing Meter Results To Laboratory Results:
Results obtained from the OneTouch Ultra Plus Flex™ Meter and laboratory tests are reported in plasma-equivalent units. However, your meter result may differ from your lab result due to normal variation. A result from your OneTouch Ultra Plus Flex™ Meter is considered accurate when it is within 15 mg/dL of a laboratory method when the glucose concentration is lower than 75 mg/dL and within 15% of a laboratory method when the glucose concentration is 75 mg/dL or higher.
Meter results can be affected by factors that do not affect lab results in the same way. Specific factors that may cause your meter result to vary from your lab result may include:
You have eaten recently. This can cause a result from fingertip testing to be up to 70 mg/dL higher than a lab test using blood drawn from a vein.1
