Displaying Results as Plasma Values or Whole Blood Values
IMPORTANT INFORMATION ABOUT PLASMA AND WHOLE BLOOD READINGS:
All LifeScan meters require a sample of whole blood from your finger or arm to give
you a blood glucose reading. But there is a difference in how certain OneTouch
®
Meters measure the amount of glucose in the blood.
A few LifeScan meters measure glucose based on the entire whole blood sample.
Others measure glucose based on only the plasma portion of the whole blood sample.
Plasma is the liquid portion of the whole blood sample after the red blood cells are
removed. Most clinical laboratories measure plasma glucose. There is a difference in
the glucose concentration in whole blood and plasma. A glucose reading from a
plasma sample is about 12% higher than a reading from a whole blood sample.
So if you are using a LifeScan meter that measures plasma glucose, readings will be
about 12% higher than those taken from a LifeScan meter that measures glucose
from the entire whole blood portion.
It's important to remember this difference when comparing glucose readings from
OneTouch
®
Meters with measurements taken at the lab. Several OneTouch
®
Meters
automatically convert readings to plasma values. Others may not, depending on the
country or locale where the meter was purchased. See the table below for more
information on each OneTouch
®
Meter.
CAUTION: Due to the difference in glucose readings related to plasma or whole blood
reporting, it is important to use the right test strips with OneTouch
®
Meters. That's
because test strips are designed to work hand in hand with the way OneTouch
®
Meters
measure glucose in the blood. For this reason, you should only use test strips purchased
in the same country or locale where you purchased your meter. This will ensure that you
are using the right test strips. As a result, your glucose readings will be as consistent and
accurate as possible. Please refer to the documentation that comes with the test strips.
Note: When communicating with devices other than OneTouch
®
Meters, the Software
assumes that these devices are plasma calibrated unless otherwise specified.
