How Long Does ETG Stay in Urine?

ETG (Ethyl Glucuronide) can typically remain detectable in urine for approximately 24 to 80 hours after alcohol consumption. The actual detection period depends on factors such as the amount of alcohol consumed, drinking frequency, metabolism, hydration, and overall health.

What Is ETG?

ETG is a metabolite produced when the body processes alcohol. Because ETG remains in the body longer than alcohol itself, ETG testing is often used to identify recent alcohol consumption.

Typical Detection Windows

Drinking Pattern	Approximate Detection Window
One or two drinks	24–48 hours
Moderate drinking	48–72 hours
Heavy drinking	Up to 80 hours or longer

Detection periods can vary among individuals.

Factors That Affect Detection

Several factors may influence how long ETG remains detectable:

• Amount consumed
• Frequency of drinking
• Body weight
• Metabolism
• Hydration level
• Kidney function

Why Courts Use ETG Testing

Many courts and monitoring programs use ETG testing because it provides a longer detection window than breath alcohol testing.

Does everyone eliminate ETG at the same rate?

No. Biological factors can influence detection times.

Can one drink be detected?

Even small amounts of alcohol may produce detectable ETG metabolites.
