RESULTS
“Do I have symptoms of high blood
glucose (hyperglycemia): fatigue,
dry mouth and skin, increased
thirst or hunger, blurry vision,
increased urination, rapid deep
breathing, or a fruity smell to
the breath?”
“What have I eaten?”
“How much have I exercised?”
“Am I ill (common cold, flu, etc.)?”
“Have I been under stress lately?”
In addition to these factors, there are
other abnormal conditions that can
affect your results.
1. Extremes in hematocrit (the
amount of red blood cells in the
blood) can affect test results.
Very high hematocrits (above 60%)
and very low hematocrits (below
25%) can cause false results.

2. Severe dehydration and
excessive water loss may cause
false low results.
