Comparing meter results to laboratory
results
Results obtained from the OneTouch® Verio® 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® Meter is considered accurate when it is
within ±20% of the lab result.
Meter results can be affected by factors that do not affect
lab results in the same way, which may cause a difference
of more than ±20%. Specific factors that may cause your
meter result to vary from your lab result by more than
±20% 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.
• Your hematocrit is above 60% or below 20%.
• You are severely dehydrated.
• For additional information, refer to the
OneTouch® Verio® Test Strip Insert.
