ETG (Ethyl Glucuronide) alcohol testing is a urine-based test that can detect alcohol consumption for up to 80 hours after drinking, depending on factors such as the amount consumed, metabolism, and hydration levels. Individuals involved in family court, probation, professional monitoring programs, or personal monitoring often use ETG testing because it provides a longer detection window than standard breath alcohol tests.
What Is ETG Testing?
ETG stands for Ethyl Glucuronide, a direct metabolite created when the body processes alcohol. Unlike a breathalyzer, which only measures current impairment, ETG testing helps determine whether alcohol was consumed within the past several days.
Who Uses ETG Testing?
Common reasons include:
- Family court monitoring
- Child custody cases
- Probation requirements
- Professional licensing boards
- Employer monitoring programs
- Personal accountability programs
How Long Does ETG Stay Detectable?
The commonly cited detection window is up to 80 hours. However, the actual detection period depends on:
- Amount consumed
- Frequency of drinking
- Individual metabolism
- Kidney function
- Fluid intake
