glucose values for your
individual treatment plan
should be determined with
your healthcare professional.
If your blood glucose test
results remain consistently
high, contact your health-
care professional.
Q.
What are the expected
blood glucose values
associated with well-
controlled diabetes?
A.
Fasting:
3.3–7.2 mmol/L
(60–130 mg/dL).
After meals (1 hour):
Less than 10.0 mmol/L
(180 mg/dL).
After meals (2 hours):
Less than 8.3 mmol/L
(150 mg/dL).

Q.
Why don’t my Meter
results exactly match the
results that I got from my
doctor’s laboratory?
A.
Many healthcare
professionals believe that
the result that you get on
your Meter should fall
within 15% to 20% of the
result obtained on labora-
tory equipment when whole
blood is tested.
5
However,
there are a number of
reasons why the blood
glucose result from your
Meter may vary even more
than 20% from a laboratory
result.
6
One of the most
common reasons is that
laboratories use serum or
plasma samples, while
home blood glucose
monitors use whole blood.
Whole blood results are
approximately 10%–12%
lower than serum or plasma
results from the same blood
sample (at average hemat-
ocrit levels of 41%–45%).
To adjust for this difference,
divide the laboratory value
by 112% or 1.12.

(Example:
a serum value of 8.3 mmol/L
is comparable to 7.4 mmol/L
whole blood value.)
