Alcohol Testing - DUI, BAT and EtG

Alcohol Testing - DUI, BAT, and EtG

Individuals convicted to or pleading to a driving while intoxicated (DUI) charge often will be required to have drug and/or alcohol testing. US Drug Test Centers can arrange alcohol or testing with one phone call.

Driving under the influence (DUI), or driving while intoxicated (DWI), is the crime of operating a vehicle while impaired by alcohol or other drugs (including recreational drugs), to a level that renders the driver incapable of operating a motor vehicle safely. People who receive multiple DUI offenses are often struggling with alcoholism or alcohol dependence and need ongoing alcohol testing.

According to the National Highway Traffic Safety Administration, alcohol-related crashes cause approximately $37 billion in damages annually. Between attorney fees, fines, court fees, ignition interlock devices, and DMV fees, a DUI charge could cost thousands to tens of thousands of dollars.

If you need alcohol testing, contact US Drug Test Centers. We have urine alcohol testing, breath alcohol testing, EtG urine alcohol testing, and EtG hair alcohol testing available at our 20,000+ locations nationwide. 

Let's look a little closer at each type of alcohol testing.

Urine Alcohol Testing

A drug test professional collects a urine sample, which is then sent to the laboratory for analysis. The urine alcohol test is not a reflection of current impairment. The pool of urine in the bladder at any given time is an accumulation of secreted urine since the last emptying of the bladder. Maybe the individual was drinking the night before. US Drug Test Centers advises caution when using urine alcohol testing to detect current impairment.

Breath Alcohol Testing

An analysis of breath gas, using a breathalyzer, gives an indirectly determined value for blood alcohol level (BAC). It's based on how much alcohol is in some portion of exhaled air. US Drug Test Centers can provide you with a breath alcohol test, or BAT, at many of our drug test centers located in all areas of the United States. The breath alcohol test will give an accurate indication of the actual blood alcohol level (BAC).

EtG Urine Alcohol Testing

Ethyl Glucuronide (EtG) or ethanol is an ingredient found in beer, wine, and liquor produced by the fermentation of yeast, sugars, and starches. EtG testing is typically used to evaluate and monitor whether an individual is abstaining from the consumption of alcohol. EtG alcohol testing detects recent usage more accurately and for a longer period of time than standard testing (80 hours). Our EtG urine alcohol is performed by our partner laboratories LabCorp and Quest Diagnostics. The urine specimens are collected at one of our many drug testing centers.

EtG Hair Alcohol Testing

In hair alcohol testing, a hair sample is taken and then measured for levels of ethanol metabolites, which are produced when alcohol is metabolized. Working with our specialty laboratory, Expertox, located in Houston, Texas, we offer EtG hair alcohol testing. This testing has a lookback period of up to 90 days. Specimen collection is available at our drug testing centers in all areas of the United States.

Every one-half inch (1/2”) of head hair is approximately equivalent to a thirty (30) day timeframe. Body hair yields an approximate six (6) month timeframe. A standard hair test is 1 ½”, or 90 days, though longer time periods can be tested, depending on the length of the hair. The hair alcohol test measures average alcohol consumption over a period of approximately three months and can provide a behavioral indication of excessive use.

More on EtG Alcohol Testing

  • EtG testing has a longer lookback period
  • EtG testing does not measure current impairment
  • EtG testing is very sensitive — incidental alcohol exposure can cause a positive test
  • EtG testing determines any consumption of alcohol
  • EtG may be run on urine specimens in conjunction with other drug testing panels
  • Tests are performed by GC/MS or LC/MS/MS on state-of-the-art equipment for accuracy and reliability
  • EtG is only evident when alcohol is consumed and is not produced as a result of fermentation
  • EtG testing allows monitoring in alcohol treatment programs
  • Ideal for zero-tolerance and abstinence situations
  • Our labs add EtS testing to the EtG testing

Ethyl Sulfate (EtS)

In addition to EtG, recent scientific studies have identified ethyl sulfate (EtS) as a second specific metabolite or biomarker of ethanol. For this reason, our labs test and report EtS, in conjunction with EtG, to confirm recent ethanol ingestion or exposure.

EtS is a specific metabolite of ethanol that is stable in urine and not subject to degradation. The detection of EtG and EtS offers greater sensitivity and accuracy for determination of recent ethanol ingestion, than by detection of either biomarker alone. Our laboratories add the EtS testing to our standard EtG testing when a confirmation test is necessary.

Any positive EtG alcohol test result means the liver has processed alcohol (ethanol). For hair testing, this goes back approximately 90 days and for urine, approximately 80 hours. EtG or EtS production may vary among individuals, and because of the long detection period, estimating the amount of alcohol consumed is not possible. In general, the greater the ng/mL value, the more recent and/or heavy the consumption has been.

US Drug Test Centers is the leader in the nation for urine alcohol testing, breath alcohol testing, EtG urine alcohol testing, and EtG hair alcohol testing. All of our testing options are available at any one of our many testing centers throughout the United States. Call today for immediate service.
