How Long Will Alcohol Stay In the System For Urine Tests?

___________________________________________

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 tests.

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 Tests

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: "how long does alcohol last in urine drug screenings"?
