Comparing the results:
When the lab tests your blood,
■
only the serum or plasma portion is
used. Your OneTouch
Meter uses only whole blood.
Comparing serum or plasma to
■
whole blood is like comparing a
temperature of 98.6˚F with the
temperature of 37˚C. To see if the
values are equal, you have to
adjust one of the results.
Whole blood results are approxi-
■
mately 12% lower than serum or
plasma results.
To compare lab results with meter
■
results, divide the lab result by
1.12.

You may still have a variation from

Assume that your lab result (plas-
ma or serum) is 224 mg/dL.
224 divided by 1.12 = 200 (the lab
value is now approximately equal
to a whole blood result).
Compare this figure to your meter
result. The two should be within
20% of each other.
In addition, if
