EtG Testing: Guides & Resources
Evidence-based articles on EtG urine testing — detection windows by drink count, cutoff level differences, false positive sources, probation and court monitoring, and the pharmacokinetics behind alcohol biomarker testing.
How Long Does EtG Stay in Urine? Full Timeline
EtG stays detectable in urine for 24–80 hours depending on drinks consumed, test cutoff, and individual metabolism. Here's the complete breakdown.
Read moreWhat Affects EtG Detection Time? 6 Key Factors
Drink count, body weight, drinking speed, hydration, cutoff level, and liver function all shift your EtG detection window. Here's how each factor works.
Read moreEtG Cutoff: 100 vs 500 ng/mL — What's the Difference?
The cutoff level changes your EtG detection window by 30–50%. Here's what 100 and 500 ng/mL mean, where each is used, and how to calculate your window at either level.
Read moreEtG False Positives: What Can Cause a Positive Without Drinking?
Mouthwash, hand sanitizer, fermented foods, and some medications can trigger EtG false positives, especially at 100 ng/mL cutoffs. Here's what the research says.
Read moreEtG Testing on Probation: What You Need to Know
EtG urine testing is standard in probation, drug court, and DUI programs. This guide covers how it works, what cutoff levels mean, and how to stay compliant.

EtG testing is highly sensitive but not infallible. Understand what it accurately detects, where it has documented limitations, and how results are interpreted.
Read moreEtG Detection: Heavy vs Light Drinking — How Much Longer?
Heavy drinking can extend EtG detection to 72–80 hours. Light drinking clears in under 24. Here's a drink-by-drink breakdown of how consumption volume affects your window.
Read moreEtG vs Breathalyzer vs Blood Test: Which Detects Longer?
EtG detects alcohol for 24–80 hours. Breathalyzers last 12 hours. Blood alcohol under 1 hour after clearance. Here's how each test works and when each is used.
