Comparing meter results to laboratory
results
Results obtained from the OneTouch Verio Flex
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 Verio Flex
Meter is considered accurate when it is within 0.83 mmol/L of
a laboratory method when the glucose concentration is lower
than 5.55 mmol/L and within 15% of a laboratory method
when the glucose concentration is 5.55 mmol/L 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 3.9 mmol/L higher than a lab
test using blood drawn from a vein.
• Your hematocrit is above 60% or below 20%.
• You are severely dehydrated.
