Extremes in hematocrit (the amount
of red blood cells in the blood) can
affect test results. Very high hemat-
ocrits (above 60%) and very low
hematocrits (below 25%) can cause
false results.

Abnormally high levels of Vitamin C
or other reducing substances will
cause false low blood glucose
results.

Normal levels of reducing
substances have little effect on
blood glucose results.
Do not use blood samples with
preservatives that contain fluoride
(gray-top test tubes). You will get
false low results.
When testing, removal of the test
strip prior to display of the blood
glucose result may give you a false
result.
Infection Control
Use universal blood precautions.
All patient samples and materials
with which they come in contact
are considered biohazards and
should be handled as if capable
of transmitting infection.
