A new study out of the University of Florida says that frequent use of
hand sanitizer may create false-positives in alcohol tests. Dr. Gary Reisfield
was inspired to do the study after coming in contact with persons who
failed an alcohol test but denied alcohol consumption. The study shows
that normal use of sanitizer - a few times a day - will not create a false
positive; however those who are exposed to it all day long (doctors, for
example) may be at a higher risk of having alcohol absorbed through the
skin, creating a false positive on tests. The study shows that other hidden
sources of alcohol are out there as well, including mouthwash and certain
cosmetics.
