Urine alcohol concentration will vary depending on the person's
metabolism and the amount of fluid in his system. For instance, a person who is
slightly dehydrated will tend to have a higher alcohol concentration in his
urine than someone who has a normal level of fluid in his system. At least one
study has indicated that a false positive for urine alcohol can occur. High
levels of sugar and acetone in the body can cause fermentation in the urine,
creating a false positive for urine alcohol.
All
things considered, the urine alcohol test is the least preferred test
available for alcohol testing. Here is the principle upon which the
BreathScanŽ digital breath alcohol tester works: the ethyl alcohol in the blood escapes through
the lung tissue into the exhaled breath. The presence of ethyl alcohol in
the breath is detectable by a color change of very sensitive chemically
coated crystals contained in the BreathScanŽ digital breath alcohol tester.
The
BreathScanŽ digital breath alcohol tester keeps the chemically coated crystals fresh in
a hermetically sealed ampoule until the digital breath tester is to be administered.
Immediately prior to use, the ampoule is ruptured by slight finger pressure
on the outer flexible clear tube to release crystals within the confines of
the tube. When the subject exhales into the tube, the fresh crystals
interact with breath vapor and change color from yellow to blue, if alcohol
is present. If all the crystals change color completely, this indicates
that the subject's blood alcohol level is at or over the level being tested
for.
The accuracy of this chemical reaction has
been scientifically documented, and is the type of reaction which
is utilized in legally substantiated test devices used by law
enforcement agencies. The BreathScanŽ digital tester detects the presence
of alcohol as low as .02%, and distinguishes low levels of alcohol
from levels in excess of .10% (legal intoxication in many states).
The crystals in the BreathScanŽ digital breath tester are unaffected by
heat and cold and the shelf life is unlimited. Each digital tester is good
until the glass ampoule inside the tester is broken.
