Well, it really depends upon a few factors. How much do you typically drink on average? "Frequency" of use (1x per day? 3-5x per day?), plus the "quantity" of alcohol you used each time, and the "length of time" (days? weeks? months?) of your alcohol consumption will vary the results of your test.

The length of time any drug stays in your system will vary. In large part, it depends on your physiological makeup (e.g., your physical height, weight, your amount of body fat, your age, current state of health, whether or not you exercise mildly-aggressively-or at all) as to how long alcohol will stay in your system. Plus, the degree of stress (i.e., your "state of mind") at the time you ingest the booze can also vary the levels in your system.

Additionally, the quality ("potency") of the alcohol you ingest determines "how long" it is detectable in your system when your urine is analyzed (tested) at the lab.

However, for most people, detectable levels (i.e., shows up as a "positive" in a laboratory drug test) of alcohol will remain in your body for 1hour to perhaps 10 or 12 hours with a maximum of 24 hours.
