How Long Does Alcohol Stay in Urine?

Alcohol may last in your urine from 12 to 36 hrs; it depends on consumption and the types of urine tests because there are some that can detect alcohol for up to 48 and 80 hours. Also It depends on a number of factors, including the amount of time before a test a person drank alcohol, what the person had to eat, their age, their weight, their gender, the total amount of alcohol consumed, and the type of test being performed.

After entering the body, alcohol passes through the stomach and intestines, and then into the blood. This process is called absorption. Next, alcohol is metabolized by enzymes. Enzymes are bodily chemicals, which break down other chemicals as they enter the body. Once in the liver, an enzyme called alcohol dehydrogenase (ADH) is responsible for changing alcohol to acetaldehyde, which is then converted to acetate.

EtG Testing


EtG detects ethyl Glucuronide in the urine, which can confirm alcohol consumption from three to four days after intake. It is also called as “80-hour test” to distinguish ethyl alcohol ingestion. It has emerged as the number one choice among service providers out there. With the continuous technology innovation, it is available across the world in these days.

Determining How Long Alcohol Stays in the Urine

Urine tests are commonly used in legal situations to determine whether someone was acting in their right mind during a certain situation. There are also career scenarios such as operating vehicles which rely on employees being lucid and checking urine is a reliable method. Under such circumstances, consuming alcohol would be illegal. Here are some instances when urine will be checked:

  • An individual’s given a ‘zero tolerance’ order
  • Someone is in rehabilitation where they are required to be abstinent
  • If there’s a relapse
  • When comparing to BAC (blood alcohol concentration)
  • Checking employees

Types of Urine Tests

When a urine test is needed to test someone for alcohol intake, two general types of tests are usually used.

  • 24-hour urine collection test, and
  • Clean catch urine test.

These tests help a person to see the amount of urine they produce in a typical day. Urine tests for alcohol can also test a person’s alcohol consumption for about up to 48 hours after the drinking occurs.

Alcohol and the Body

Upon consumption, alcohol enters the stomach and intestines. Once the substance enters the capillaries surrounding the stomach and small intestines, it enters passageways that lead to the portal vein, which passes through the liver and branches out into the capillaries.

Once the substance enters the bloodstream, it affects all major organs in your body, including the heart and brain. Alcohol reaches all body tissues except bone and fat.

Factors That Influence Alcohol Absorption

Genetic, environmental, and physical and mental health factors control alcohol metabolism and elevate your blood alcohol content – the percentage of alcohol in the blood.
