RESULTS
glucose levels can change significantly
within short periods of time.
◆ Factors such as a low or high hematocrit
(the percentage volume of red blood
cells in your blood). For example, if your
hematocrit is too low (below 25%) or too
high (above 60%).
◆ Severe dehydration (loss of body fluid) may
also cause meter results to be different
from a laboratory result. Repeated vomiting
or diarrhea, both of which can occur when
your glucose is very high, can cause this.
Your blood may become thick, with not
enough liquid to properly wet the test strip.
This may cause your meter to give false low
blood glucose results.
◆ If you test at a very low or high tempera-
ture or a low or high relative humidity or
some other extreme environmental con-
dition. If you test under these conditions,
repeat the meter test in a climate-con-
trolled place as soon as possible. The
operating temperature is 50–95°F. The
operating humidity is 10–90%. You
should always test within these ranges.
◆ You may also get inaccurate results if
you test when both the temperature and
relative humidity are near the limits
defined above. If you test under these
conditions, repeat the meter test in a
climate-controlled place as soon as
possible.
◆ Conditions affecting circulation to the
hands may also lead to inaccurate
results. These include shock, some
drugs called vasoactive agents, and
Raynaud’s disease.
