EtG
(Ethyl Glucuronide)
Specimen:
Urine,
5 mL
Method: Liquid
Chromatography/Tandem Mass Spectrometry (LC/MS-MS)
Cutoff: 250
and 500 ng/mL
Reporting limits: 100
to 10,000 ng/mL
Ingested alcohol
(ethanol) is metabolized via several identified pathways and
a minor (0.02%) but important non-oxidative pathway produces
ethyl glucuronide (EtG), which is excreted in the urine. It
has also been detected in blood, other body fluids, hair and
post-mortem tissue.
EtG may be detected
in urine for up to 80 hours after the elimination
of alcohol from the body, and detection of EtG in urine indicates
recent consumption of alcohol. It is a useful tool
in numerous settings, including: alcohol and drug treatment
(to detect lapse/relapse and for motivational feedback);
safety sensitive work settings where use is dangerous; other
circumstances where alcohol use may be risky (e.g. such as
driving, work-place, pregnancy or monitoring physicians or
other professionals who are in recovery and working); or
for resolving forensic questions. If the question of
recent alcohol consumption has to be answered with a “yes/no”,
such as for determining relapses, the analysis of EtG in
urine is the latest and best test. Our testing method
employs the latest and best method available. Advantages
of EtG include:
Ø EtG
is a direct metabolite of alcohol, is more accurate than indirect
measures (MCV, CDT, GGT, etc) and not a product of in vitro fermentation.
Ø For
abstinence testing, EtG is the definitive test.
Ø EtG
is superior to urine alcohol because it remains in the urine longer
and therefore has a longer window of detection (3-4 days)
Ø EtG
is a stable compound detectable in the urine, blood, hair and post-mortem
tissue
Ø EtG
can be used to determine whether or not alcohol has been recently
consumed
