What is ETG?

EtG, or Ethyl Glucuronide, is a direct metabolite of ethanol (alcohol) that the body produces after alcohol consumption. Unlike measuring alcohol itself—which leaves the body relatively quickly—EtG remains detectable for a longer period, making it a reliable biomarker for recent alcohol use. In point-of-care rapid toxicology screening, EtG tests provide fast results at the collection site, allowing programs to identify alcohol exposure even after the effects of intoxication have subsided.

EtG testing is commonly used in workplace programs, treatment settings, court-ordered monitoring, and recovery programs where abstinence or recent use must be verified. Because EtG indicates alcohol consumption, not impairment, it helps organizations monitor compliance, assess risk, and make timely decisions. Rapid EtG screens are valued for their simplicity, quick turnaround time, and ability to detect drinking within approximately the past 24–72 hours, depending on the individual and amount consumed.

Legal Status:

For many private employers, there is no universal legal requirement to conduct drug or alcohol testing. However, under the Drug-Free Workplace Act of 1988, federal contractors and grantees — and many entities receiving federal funds — must commit to providing a “drug-free workplace,” which often includes drug (and sometimes alcohol) testing as part of their compliance obligations.

For jobs regulated by the U.S. Department of Transportation (DOT) or other safety-sensitive federal industries (e.g., commercial drivers, aviation maintenance, railway workers), mandatory rules apply. For example, the DOT’s regulation known as 49 CFR Part 40 sets out when and how drug and alcohol testing must be done for safety-sensitive positions.

The Americans with Disabilities Act (ADA) also plays a role: employers are allowed to maintain alcohol- and drug-free workplace policies, and to conduct testing, but they must respect certain protections — especially for rehabilitated individuals or those in recovery.
