(hyperglycemia)?"
"What have I eaten?"
"How much exercise have
I had?"
"Am I ill?" (i.e., common
cold, flu, etc.)
In addition to the common
factors listed above which
cause real variations in
blood glucose results, there
are certain abnormal
conditions which will
interfere with the accuracy
of your blood glucose
monitoring results. These
limitations are described
below and should be
discussed with your
physician.
Extremes in hematocrit (the
amount of red blood cells in
the blood) can affect test
results. High hematocrits
(above 60%) cause inac-
curately low results. Very
low hematocrits (below
25%) can also cause
inaccurately low results.

Severe dehydration and
excessive water loss may
cause inaccurately low
results. This has been
reported in the medical
literature for leading
blood glucose monitoring
products. Severe
1,2
dehydration can lead to
many serious medical
complications. One
complication which is
of particular importance
in diabetes management
is a "hyperglycemic-
hyperosmolar" state, with
or without ketosis, which
may be life-threatening if
left untreated. The fol-
lowing are some of the
