What Is an ETG Test? Urine Alcohol Testing Explained

by | Sep 29, 2026 | Employer Solutions

  • The EtG urine test has become a prominent form of testing for alcohol use, offering a longer window of detection than other types of alcohol testing, up to 72+ hours following the consumption of alcohol.
  • An EtG test checks for an ethyl glucuronide metabolite, which can be detected in urine long after alcohol is no longer present in the body.
  • ARCpoint Labs of Omaha offers professional laboratory test collection sites at our lab and at businesses throughout the Omaha area.

An EtG test can tell whether someone has consumed alcohol for as long as 48-72 hours after having one or more alcoholic beverages. EtG testing offers an uncomplicated way to detect whether someone has been drinking alcohol, with a longer window of detection than either a breathalyzer or blood test. EtG stands for ethyl glucuronide, a metabolite or small molecule made when ethyl alcohol is processed through the liver and combined with glucuronic acid made from glucose. That metabolite can remain detectable despite alcohol no longer being present. ARCpoint Labs of Omaha offers EtG testing and other test collections in Omaha.

What Is an ETG Test?

An EtG test is conducted through a sample of an individual’s urine, where ethyl glucuronide metabolites can be found. The test looks for or rules out alcohol metabolites, not impairment at the time the sample is taken.

How Does an ETG Urine Test Work?

An ETG urine test is easy. The individual provides a urine sample either at our facility or at an alternative collection location.

Sometimes this is done under supervision, or the client may be asked to place personal items in a locker before entering the restroom or collection area. This helps ensure the sample is not contaminated, adulterated, substituted, or diluted, while keeping the individual’s belongings safe. Testing for an alcohol metabolite is highly beneficial and can offer information after alcohol itself has left the body, which other methods of testing cannot. EtG testing is becoming a more prominent, highly accurate method for alcohol testing.

When Is an ETG Alcohol Test Used?

There are many reasons an EtG alcohol test may be given, including routine testing of employees for alcohol use in the workplace. It is used for court-ordered alcohol testing and monitoring requirements of probation.

An individual may ask for an EtG test as proof of no alcohol intake for their own personal accountability. An EtG test may be run without a doctor’s order or court order. Anyone can request the test.

What to Expect During ETG Testing

Providing a sample collection is quite straightforward. We will provide pre-collection instructions when an appointment is scheduled. We will provide other sample collection instructions at the time of collection, and they may differ depending on who is requesting the test. Individuals should confirm any test requirements with our staff and ask any questions before providing a sample.
