How Long Can A Urinalysis Detect Alcohol?
Various organizations and companies have established random alcohol tests and employ urine tests to check
for alcohol in their employees.
Obviously, a number of people who work in such companies and organization are asking the following: "how
long can a urinalysis detect alcohol"?
Please continue reading for an answer to this and other relevant questions pertaining to alcohol testing in
general and urine alcohol testing in particular.
The Employment of Urine Alcohol Tests In the Workplace
Many people who drink alcoholic beverages work for employers who have random alcohol tests.
While many of these places of employment use saliva tests, blood tests, or breathalyzer tests, many of them,
however, use urine tests to check for alcohol.
Under these circumstance, it seem quite understandable that employees might ask the following: "how long can a
urinalysis detect alcohol"?
With so many different types of tests that are available, it may be asked why urine tests are employed.
Urine alcohol tests are used for the following reasons:
- They are relatively inexpensive
- They are the most likely of all drug-testing methods to withstand legal challenge
- They have a high assurance of reliable results
- They provide the most flexibility in testing different drugs, including alcohol and nicotine
The All-Important Blood Alcohol Content Level
Without a doubt, people who are employed at work places that use urine alcohol tests often ask the following
question: how long can a urinalysis detect alcohol?
To help answer this question, please take the following information into account.
The amount of alcohol in the blood is called blood alcohol concentration or blood alcohol content level
Alcohol is metabolized at the rate of .015 of (BAC) every hour.
For example, an individual with a BAC of .15 (almost twice the legal limit for driving in all 50 states) will
have no measurable alcohol in his or her blood 10 hours after consuming the last drink (.15 divided by .015 =
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 blood alcohol concentration of .08 or higher, she or he is considered to be driving "under
the influence" (DUI).
An individual with a blood alcohol content level of .08 will have no measurable alcohol in the bloodstream
roughly 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 approximately 48 hours after an individual has
With the EtG Urine Alcohol Test, conversely, the presence of EtG in the urine reveals 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
As a result, it can be shown that a urine alcohol test employing EtG is a more accurate indicator of the recent
consumption of alcohol as compared to simply measuring for the existence of ethanol alcohol (which is done by
numerous urine alcohol tests).
Let's use one of the above examples to further illustrate the ramifications of the EtG Urine Alcohol Test.
As noted above, a person with a blood alcohol concentration of .15 will have no measurable alcohol in his or her
bloodstream 10 hours after the last drink.
With the EtG Urine Alcohol Test, nevertheless, 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).
A moment's reflection on what this means will be worthwhile. No, the EtG Urine Alcohol Test cannot show how much
alcohol a person ingested, but it can, by way of comparison, detect alcohol consumption after the alcohol has been
metabolized by the body.
This is a point of considerable importance: If the individual, for instance, has articulated that he or she has
discontinued drinking for any period of time, the EtG Urine Alcohol Test will reveal that he or she is not being
Conclusion: How Long Can A Urinalysis Detect Alcohol?
As they say when something becomes obvious, the writing is on the wall.
That is, as long as companies and organizations lose substantial amounts of money and "person-hours" to alcohol
abuse, they will continue to employ random alcohol tests.
While many of these workplaces use blood tests, breathalyzer tests, or saliva tests, a number of them, however,
use urine tests to check for alcohol. Why is this important?
This is significant mainly because EtG urine alcohol tests can detect alcohol in the urine 80 hours after the
ethanol alcohol has been metabolized by a person's body.
So the moral of the story is this: if you are a drinker and your employers uses random urine alcohol tests, it
might be a good idea to abstain from drinking alcohol during the work week.
Then you won't have to ask the following: "how long can a urinalysis detect alcohol"?
