A number of individuals who drink alcoholic beverages work for employers that have initiated random urine
alcohol tests. It thus becomes understandable when many employees ask the following question, “how long does
alcohol last in urine drug screenings”?
Why Urine Alcohol Tests Are Used in the Workplace
Many individuals who drink alcoholic beverages work at organization, agencies, institutions, and companies that
have established a random alcohol testing program. Many of these companies and workplaces use urine alcohol
Why urine alcohol tests? Because urine alcohol tests are relatively inexpensive and they are the most likely of
all drug-testing methods to withstand legal challenge.
Not only this, but urine alcohol tests have a high assurance of reliable results and they provide the most
flexibility in testing different drugs, including alcohol and nicotine.
Obviously, individuals who are employed at work places that use urine alcohol tests many times ask the following
question: how long will alcohol stay in the system for urine tests?
To help answer this question, consider the following information.
Blood Alcohol Concentration Level
The amount of alcohol in the blood is called blood alcohol content or blood alcohol concentration (BAC). Alcohol
is metabolized at the rate of .015 of (BAC) every hour.
For instance, a person with a BAC of .15 (this BAC is almost twice the legal amount when driving) will have no
measurable alcohol in the bloodstream ten hours after the last drink (.15 divided by .015 = 10).
If a person is driving and gets pulled over by the police, the police can administer a blood alcohol test
(usually done by a breathalyzer test).
If the person has a BAC of .08 or higher, he or she is considered to be driving “under the influence” (DUI). A
person with a BAC of .08 will have no measurable alcohol in the bloodstream 5.33 hours after the last drink (.08
divided by .015 = 5.33).
The EtG Urine Alcohol Test
With some urine alcohol tests, alcohol can be detected up to around 48 hours after a person has ingested
alcohol. With the EtG Urine Alcohol Test, however the presence of EtG in the urine demonstrates that ethanol
alcohol was ingested within the past 3 or 4 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 (as is done many
other urine alcohol tests).
Let’s use one of the above examples to further illustrate the ramifications of the EtG Urine Alcohol Test. As
stated above, a person with a blood alcohol concentration of .15 will have no measurable alcohol in his or her
bloodstream ten hours after the last drink.
With the EtG Urine Alcohol Test, however, the presence of EtG in the urine reveals that ethanol alcohol was
consumed within the past 80 hours or so which could mean many hours after the ethanol alcohol has been metabolized
by the body.
Think this through for a moment. No, the EtG Urine Alcohol Test cannot tell how much alcohol a person ingested,
but it can, however, detect alcohol consumption after the alcohol has been metabolized by the person’s body.
The significance of this is that if the person, for instance, has stated that he or she has stopped drinking for
any period of time, this test will show that they are not telling the truth.
Conclusion: How Long Will Alcohol Stay In the System For Urine
As outlined above, EtG urine alcohol tests can detect alcohol in the urine up to 80 hours after the alcohol has
been metabolized by an individual’s liver.
Taking this into consideration, the moral of the story is this: if you drink alcohol, if you work for an
employer that has implemented random urine alcohol testing, and if you want to keep your job, it seems reasonable
to suggest that you abstain from drinking alcohol during the work week. Then you won’t have to ask the following:
