There are a wide range of factors which determine the duration for which alcohol traces can be detected in your urine or urinary system. It depends on how long ago you consumed the alcoholic beverage, your age, your weight, what food you have consumed and your typical or standard rate of alcohol intake.


There are two ways to collect urine for testing traces of alcohol:

  • Clean catch urine specimen.
  • 24 hour urine collection.

How long does alcohol stay in your urine?

Have you ever wondered the amount of time alcohol traces can be found from urine? Well the answer to the question is that alcohol can be detected up to 12 to 36 hours however modern urine tests can detect alcohol residue if present even after 48 hours. As mentioned above certain factors determine the amount of time within which it can be traced.

It must also be mentioned here that by undertaking a test called “EtG” a related chemical called Ethyl Glucuronide can be detected which is instrumental in indicating the presence of alcohol in the urine system if it was consumed within 80 hours.

EtG or Ethyl Glucuronide                 

This is the most revolutionary way to determine the answer to how long does alcohol stay in your urine. With the advancements in technology this technique is readily available and is called the 80 hour test. The uniqueness of this test is that despite lost traces of ethanol from alcohol EtG is a direct indicator that alcohol was consumed.

Other tests

Another very important and useful test which determines how long does alcohol stay in your urine is the testing of hair follicles which will easily indicate that alcohol was consumed even after three months of the consumption. The saliva test can also determine the presence of alcohol after 12 days of the person drinking alcohol.
