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.
Example:
■
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.
You may still have a variation from
the result because blood glucose lev-
els can change significantly over short
periods, especially if you have recent-
ly eaten, exercised, taken medication,
or experienced stress.
