The amount of time alcohol stays in urine will depend on how fast it’s absorbed and metabolized in the body. This can depend on a variety of personal, biological, and genetic factors.
Detecting Alcohol In Urine
After drinking, alcohol will generally remain in urine for 10 to 12 hours on average. If you take a drug test capable of screening for alcohol metabolites, this can detect alcohol use for up to 48 hours.
What Factors Can Affect Alcohol Detection In Urine?
Not all bodies absorb or metabolize alcohol at the same rate. Using multiple drugs at once, being a heavy drinker, or being of older age can affect how long alcohol will stay in the body.
Primary factors that can affect how long alcohol stays in urine:
- amount of alcohol consumed
- how often you drink
- alcohol dependence
- liver and kidney function
- overall health
- metabolic rate
Eating food before or while you’re drinking can affect alcohol absorption. This is also true for drinking water.
