RESULTS
“Do I have symptoms of high blood
glucose (hyperglycemia): fatigue, dry
mouth and skin, increased thirst or
hunger, blurry vision, increased uri-
nation, 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.
