EtG Test - EtG / EtS - Ethyl Glucuronide Ethyl Sulfate Alcohol Drug Test


Also known as "The 80 Hour Alcohol Test"


EtG/EtS is a laboratory based urine test that will detect the presence of alcohol up to 80 hours after consumption. The EtG alcohol test is is sometimes referred to as “The 80 Hour Alcohol Test” and tests for Ethyl Glucuronide and Ethyl Sulfate.

For more information on the EtG Test and EtG Testing see EtG Information below.

Ethyl Glucuronide (EtG) and Ethyl Sulfate (EtS) are metabolites produced by the body only after the consumption of alcohol has been consumed. EtG and EtS are excreted from the body in various ways. Our laboratory is one of only a few laboratories in the country that has the ability to identify and quantify these two metabolites.

EtG / EtS Test - Ethyl Glucuronide Ethyl Sulfate Alcohol Testing


EtG and EtS testing will allow you to quantify alcohol consumption up to 80 hours afterward.

This is a LCMSMS Lab Test (a.k.a. LC-MS-MS or LCMS, LC-MS) for professional laboratory testing of human urine for the presence of metabolized alcohol - EtG Test.

In the United States, alcohol abuse has reached epidemic proportions. The overall risks to physical and mental health can be devastating. More severe are the tens of thousands of fatalities annually which are attributed directly to alcohol intoxication. The costs associated with enforcing laws, prison systems, governmental programs and non-profit funding is exorbitant.

Until recently, testing methods for alcohol consumption have remained unchanged and unreliable. Urine ethanol has it’s flaws such as false positive results. The window of detection for breath alcohol testing is small and always had to be confirmed by laboratory blood testing which may not occur for many hours after suspected consumption.

Our Laboratory has changed the face of alcohol testing industry. We have the capability of measuring consumption up to 80 hours afterward. Ethyl Glucuronide (EtG) and Ethyl Sulfate (EtS) are metabolites produced by the body only after alcohol has been consumed. EtG and EtS are excreted from the body in various ways and our Laboratory is one of the few laboratories in the country able to identify and quantify these two metabolites.

The New Front Runner: EtG & EtS

  • EtG and EtS are easily quantifiable with Liquid Chromatography Mass Spectrometry not GC/MS and proper measurement of both metabolites can differentiate consumption vs. environmental exposure

  • EtG/EtS confirmation is the perfect testing method for ‘Zero Tolerance’ situations and an effective and noninvasive tool for voluntary treatment facilities and school systems

  • EtG/EtS can not be masked by illnesses i.e. urinary tract infections, and false positive results from diabetes are eliminated.

The Most Advanced Technology Available

Our Laboratory has the most accurate technology available for the drug and alcohol testing community. Liquid Chromatography Mass Spectrometry (LC/MS/MS) is research quality laboratory equipment, and can accurately quantify substances well below cutoff levels. This technology surpasses Gas Spectrometry, which in the past had been labeled the ‘gold standard’. Western Slope Laboratory currently owns and operates 4 LC/MS/MS and we are constantly investing in our technology.

Collection Process & Shipment

The urine collection device developed by our Laboratory is as innovative as the testing process. An absorbent material encased in a sealable tube. The design provides ample volume of specimen for the lab and is less bulky than urine transport cups. Our collection device minimizes accidental spills or specimens destroyed in transport . Because our Laboratory’s collection devices are compact and lightweight, this reduces transportation costs.

EtG Info - What is EtG?

Ethyl Glucuronide (EtG) is a direct metabolite of ethanol alcohol. The presence of EtG in the urine can be used to detect recent alcohol consumption, even after the ethanol alcohol is no longer measurable.

Consequently, the presence of EtG in the urine is a definitive indicator that alcohol has been ingested.

Traditional laboratory practices typically measure the amount of alcohol present in the body. Depending on the amount of alcohol that has been consumed, this method usually reveals alcohol ingestion within the past few hours.

The presence of EtG in the urine, on the other hand, demonstrates that ethanol alcohol was ingested within the past three or four days, or roughly 80 hours after the ethanol alcohol has been metabolized by the body.

As a result, it can be determined that a urine alcohol test employing EtG is a more accurate indicator of the recent consumption of alcohol as opposed to simply measuring for the existence of ethanol alcohol.

Accuracy and Reliability of the EtG Urine Alcohol Test

Our lab uses the most advanced, accurate, and precise equipment and technology that is available (LCMS or LC/MS/MS) to sift through, validate, and quantify the presence of EtG. Under these stringent parameters, the EtG urine alcohol test provides highly accurate results.

The Key Benefits of Using the EtG Test Include the Following:

  • EtG tests detect recent usage more accurately and for a longer time period compared with standard testing

  • EtG testing is a great match for abstinence and zero tolerance circumstance

  • EtG tests provide an accurate and reliable indication of alcohol ingestion within the previous 3 to 4 days

  • EtG is only detectable when alcohol is ingested and is not produced as a result of alcohol fermentation

  • EtG testing facilitates monitoring in alcohol treatment programs

  • EtG test function as an early warning system that can identify relapse patterns

  • EtG tests can be accurate and reliable when performed by LC/MS/MS on state of the art equipment

  • Some labs can provide thirty-six hour turnaround time from receipt of the urine specimens

  • EtG tests can be run on urine specimens in conjunction with other drug testing methods

  • Top-rate labs can provide results via fax, the U.S. mail, and via the Internet

Urine Alcohol Test EtG: Parting Thoughts

As long as employers lose considerable amounts of money and "person-hours" to alcohol abuse, they will continue to employ random alcohol tests. As a consequence, a number of organizations and companies have implemented random EtG urine alcohol tests as part of their alcohol and drug screening protocol.

Urine alcohol tests with EtG are not only accurate and reliable, but they also provide many screening benefits. When their relatively inexpensive cost is added to the equation, moreover, EtG urine alcohol tests become a reasonable and cost-effective methodology for employee alcohol screening and testing.

Some Interesting Facts:

  • Alcohol abuse effects can be physical and psychological for the drinker. The effects of alcohol abuse not only have consequences for the drinker but for those around her or him as well. Alcohol abuse effects can be immediate as well as long term effects of alcohol abuse.

  • What causes alcohol abuse? Many factors influence a person's initial alcohol use. Personality characteristics, peer pressure, and psychological stress can all contribute to the early stage of alcohol abuse. These factors are less important as alcohol use continues and the person repeatedly experiences the potent pharmacological effects.

  • Hangovers are generally more common in light to moderate drinkers than heavy and chronic drinkers, suggesting that binge drinking can be as threatening as chronic drinking. Any man who drinks more than five drinks or any woman who has over three drinks is at risk for a hangover.

  • According to the alcohol abuse research literature, U.S. males are four times as likely as females to be heavy drinkers. Interestingly, this statistic holds for people of all ages. Unfortunately, this probably means that four times as many men as women will become abusive in their relationships, will experience alcohol-related problems at work, and will become alcohol dependent
