Blood glucose levels can change
significantly over short periods,
especially if you have recently
eaten, exercised, taken medication,
or experienced stress.
3 In addition,
if you have eaten recently, the blood
glucose level from a fingerstick can
be up to 3.9 mmol/L higher than that
of a venous sample (blood drawn
from a vein) used for a laboratory
test.
4 Therefore it is best to fast for
eight hours before doing the compar-
ison tests. Factors such as a high or
low hematocrit (amount of red blood
cells in the blood) or severe dehydra-
tion (loss of body fluid) may also
cause a meter result to be different
from a laboratory result. For more
detail, see pages 41 and 42.
Expected Test Results (Target Range)
Your test results will vary some-
what from test to test. Blood glu-
cose levels change throughout the
day. The types and amounts of food
you eat, your activity and stress
levels, and how much insulin or
other medication you take affect
your blood glucose levels. If you
are controlling your diabetes well,
your test results should fall within
a personal target range recommend-
ed by your healthcare professional.
Once you have established your tar-
get range, you will be able to detect
when your results are high or low
and can take action with advice
from your healthcare professional.
