In addition to the common factors
listed above which cause real
variations in blood glucose results,
there are certain abnormal condi-
tions which can 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 inaccurately 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

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 un-
treated. The following are some
of the factors which could lead
to severe dehydration:
