How long does alcohol stay in your urine for a drug test? I pleaded guilty to a DUI and am on probation.

Asked about 3 years ago - Canton, GA

How long does alcohol show up in your urine system for a urine test? My probation officer called me in for a drug test screen on a urine sample. I plead guilty to DUI. I work in a restaurant that serves alcohol, which was brought out in court and deemed acceptable.

I met with my probation officer a few days after my court date, and everything seemed routine and fine. Then a week later I get called in to take a drug test.

I know they test for drugs; if they test for alcohol via the urine sample, how long after alcohol is consumed does it show up in a urine sample? This is in Cherokee County.

    Answered . Alcohol can last anywhere from 12-36 hours in your urine. Whether alcohol will show up will depend on how long before the test you drank, how much you drank and whether they are testing for EtG and EtS or just alcohol. If you had a glass of wine the night before they probably won't find anything. If, however, you were intoxicated it may show up.

    Urine testing can show the presence of alcohol, but only until the alcohol is out of the blood and the bladder is emptied - 6 to 12 hours after the end of drinking in most cases. Longer if you drank a lot of alcohol. This detection time can be extended by another ten hours if they test for ethyl glucuronide (EtG) and ethyl sulfate (EtS).

    There are several biochemical markers associated with significant alcohol consumption that can show up for a long time after the actual alcohol is out of the system. Generally, the tests for these markers are blood tests, not urine tests. Carbohydrate-deficient transferrin (CDT) can show alcohol use for 3-4 weeks after consumption. Gamma glutamyltransferase (GGT) detects chronic drinking for 2-6 weeks after the person stops drinking. A mean corpuscular volume (MCV) test can show chronic drinking for several months after stopping.

    Answered . I can't imagine you showing up while under the influence of alcohol since consumption of alcohol while you are on probation for DUI is often a condition of probation which you would then have violated. Urine testing is seldom, if ever done for ethanol. Most likely, they will be testing for MJ. So, being made aware that random testing is upon you govern yourself accordingly. Your Local DUI lawyer shold know much more about the local PO policies. If not, find another lawyer.
