EtG/EtS Alcohol Testing
ARE THEY DRINKING? WE'LL FIND OUT
EtG is a direct metabolite of alcohol (ethanol). Its presence in urine may be used to detect recent ethanol ingestion, even after ethanol is no longer measurable. The presence of EtG in urine is an indicator that ethanol was ingested and can be detected in urine for up to 80 hours after ingestion. EtG is only evident when ethanol is ingested and is not produced as a result of fermentation.
In addition to EtG, recent scientific studies have identified ethyl sulfate (EtS) as a second specific metabolite or biomarker of ethanol. For this reason, RTL tests and reports EtS, in conjunction with EtG, to confirm recent ethanol ingestion or exposure. The detection of EtG and EtS offers greater sensitivity and accuracy for determination of recent ethanol ingestion, than by detection of either biomarker alone.
RTL utilizes the most sophisticated, sensitive, and specific equipment and technology available. After first screening for presumptive positives, we quantitatively confirm EtG/EtS by LC/MS/MS (liquid chromatography/mass spectrometry/mass spectrometry). This combination of separate screening and confirmation methods provides highly accurate alcohol biomarker test results.
- Detects recent ingestion more accurately and for a longer period of time than standard alcohol tests
- Provides greater sensitivity and accuracy by measuring both EtG/EtS
- Ideal for zero tolerance treatment programs and abstinence enforcement
- EtG/EtS tests may be run conveniently with other RTL drug screens
- Fast results (48 hours1 negative, 48-72 hours positive)
