Comparing meter results to laboratory
results
Results obtained from the OneTouchVerio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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 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 haematocrit is above 60% or below 20%.
• You are severely dehydrated.
