Small traces can be detected for about: 12-24 hours from last consumption (depending on the amount consumed), But some traces of metabolites can be detected up to 80 hours later with the use of highly sensitive testing equipment (ETG Test).
How Long Does Alcohol Stay In Your Urine?
Alcohol consumption can cause considerable problem for you if you happen to appear for a drug test the day after, because it refuses to vanish completely from the human body within a day. In fact, sensitive assays are available which can detect the traces of metabolites formed after breaking down the alcohol for as long as four days after the last drop of alcohol have entered your body. The good thing is that it is not possible to detect direct evidence of alcohol in the urine if a few hours have passed after the last glass of alcohol that you might have drank. However, these sensitive assays make use of the presence of these trace metabolites in the urine to confirm that a person had indeed drank alcohol in the past couple of days. Thus, the answer to the query about how long does alcohol stay in your urine depends upon a number of factors all of which act together to determine its duration.
The alcohol that you consume makes its way through the gastrointestinal tract, with 90% of it being processed by the liver to break it down to acetic acid or vinegar. However, another 10% gets eliminated from the body by the way of the kidneys and the lungs. The kidneys eliminate a majority of the 10% of alcohol that the body excretes through urine, breath and sweat. However, the problem with detecting the presence of alcohol in the urine is that in remains there for an extremely short duration of time. In fact, alcohol depresses the action of the hormone Vasopressin that plays the key role in regulating the water content in the body. Depression of this hormone leads to an increase in frequency or urination, which helps in removing the alcohol from the body in around an hour and twenty minutes since the time of ingestion. Thus, the answer to the query regarding how long does alcohol stay in your urine is that it remains for only a couple of hours after the last drink you have had. But the detection time for smaller traces of alcohol in the urine is about: 12 to 24 hours after last consumption.
Taking a ETG Urine Test?
The relief that you may have experienced after learning about the above aforementioned fact is going to be extremely short-lived when you realize that the presence of ethyl alcohol in your urine is not the only way to determine whether you have been drinking in the last couple of days or not. This is because an extremely sensitive assay, going by the name of ETG Urine test for Alcohol, which identifies the presence of a by-product of ethanol metabolism, ethyl glucuronide in the urine sample. This metabolite remains in traceable amount in the urine of a person having exposure to alcohol for around 80 hours since the time of any such exposure. Thus, if you have been drinking, then taking this test is going to come up with a positive result even after four days since you have had your last sip. Thus, the duration for how long does alcohol stay in your urine is 80 hours in case of this ETG sensitive assay.
However, this assay is exceedingly sensitive and it can detect trace amounts of alcohol, which may have entered your body due to exposure to any product containing alcohol such as after-shave lotions, and various cosmetic products. Therefore, it can also give a large number of false positive due to which it is better to make it clear to the authority about the products you use that might contain alcohol in case of a positive result on your urine sample. You should particularly do so if you have not been drinking any time in the past four days. However, you need to be always on your toes regarding how long does alcohol stay in urine to be able to come out on top of all these tests, and not get busted.
How Detection Times Can Vary:
The rate at which the body absorbs alcohol and metabolizes it depends upon a number of diverse factors. The gender of the person, as well as, their bodyweight plays a large role in determining the extent of effect any particular amount of alcohol is likely to have on them. This is because the water content is comparatively higher in men compared to women, which helps in diluting the alcohol and reducing its rate of absorption into the bloodstream. Moreover, a higher bodyweight helps in coping better with the effects of alcohol. Apart from these, the rate of metabolism and the age of the person concerned play a crucial role as well. In addition to that, the amount of alcohol consumed and the food consumed immediately before or along with it determines the amount of alcohol that will make its way into the bloodstream. Protein-rich food and water helps in lessening the rate of absorption of alcohol by the epithelial cells of the stomach. Thus, you need to keep these factors in mind while trying to determine how long does alcohol stay in urine.
You should consider pacing your drink and leave some time out to ensure that the body gets ample opportunity to eliminate the alcohol, and particularly so if you need to drive back on your own after a hard night of partying and boozing. A common misconception abounds that certain types of drinks lead to lesser amount of alcohol showing up on the urine alcohol tests. This is completely unfounded, and you should know better now that you have gone through all the scientifically proven factors determining that how long does alcohol stay in your urine.
