Comparing the results:
When the lab tests your blood, only
the serum or plasma portion is
used. Your ONE TOUCH
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—in order to
see if the values are equal, you
have to adjust one of the results.
Whole blood results are
approximately 12% lower than
serum or plasma results.
To compare lab results with meter
results, divide the lab result by 1.12.

Assume that your lab result

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
levels can change significantly over
short periods, especially if you have
recently eaten, exercised, taken
medication, or experienced stress.
In addition, if you have eaten
