Phosphatidylethanol (PEth), a biomarker that reflects alcohol intake, can be detected up to 14 days in urine. Alcohol can be detected from 12 to 24 hours in the breath, as well as in saliva.
Once the alcohol has entered your bloodstream, your body will metabolize a certain amount of alcohol every hour, depending on the individual and other factors like liver size and weight.

How Long Does Alcohol Stay in Your System (Blood, Urine and Saliva)? Alcohol stays in your system for between one and three hours, but urine tests and breathalyzers detect alcohol use for up to 24 hours.
Alcohol can stay in your system between 6-72 hours in most cases, depending on the detection test used. Alcohol detection tests can measure alcohol in the blood for up to 12 hours, on the breath for 12 to 24 hours, urine for 12-24 hours (72 or more hours after heavier use), saliva for up to 12 hours, and hair for up to 90 days.

Blood test: 12 hours. Breath test: 24 hours. Saliva test: 48 hours. Urine test: Five days. Hair test: 90 days.

A person can typically measure it within 30–70 minutes of drinking. The number of drinks a person has, along with their weight and sex, can affect their BAC levels. The higher the...
