How long does alcohol stay in your urine?
But alcohol byproducts, like ethyl glucuronide (EtG), can be detected in urine for up to 3 days after a person鈥檚 last drink. Other lab tests might also test urine for ethyl sulfate (EtS). EtS is another type of metabolic substance that detects alcohol in a person鈥檚 system.
What is the alcohol content of urine?
Urine alcohol content is sometimes used to estimate a person鈥檚 blood alcohol content. The amount of alcohol in a person鈥檚 urine is approximately 1.33 times greater than the amount of alcohol in their bloodstream. For accuracy, at least two urine samples are usually collected 30 minutes to an hour apart.
How long does alcohol stay in your system on an ETG?
Many people believe that an alcohol metabolite called ethyl glucuronide can be detected by ETG tests for about 80 hours. But a 2007 study published in the journal Alcohol and Alcoholism found that ETG tests failed to detect alcohol more than 26 hours after consumption. Most drug tests detect alcohol for between two and 24 hours.
Does alcohol show up in a urine test?
However, the amount of alcohol present in the urine is typically greater than the levels of alcohol in the bloodstream. This can sometimes lead to tests that conclude a person drank more alcohol than they actually consumed. For the most accurate results, collect at least two urine samples around 30 minutes to 1 hour apart.
