About the ETG Elimination Time Calculator
The ETG Elimination Time Calculator helps estimate how long Ethyl Glucuronide (ETG) — a byproduct of alcohol metabolism — stays detectable in your urine. ETG testing is widely used for probation monitoring, workplace testing, and clinical alcohol abstinence verification. Because ETG can remain in your system much longer than blood alcohol, understanding your detection window is important.
How the ETG Elimination Formula Works
Our calculator combines key biological and lifestyle factors to produce an approximate detection range:
- Number of drinks: The more alcohol consumed, the longer ETG stays detectable.
- Time since last drink: The calculator subtracts this value from total ETG clearance hours.
- Body weight and gender: Affect alcohol metabolism rate.
- Test sensitivity: 100 ng/mL cutoffs detect alcohol longer than 500 ng/mL cutoffs.
- Metabolism speed: “Fast” users eliminate ETG slightly quicker.
ETG Detection Time Table
| Drinking Level | 100 ng/mL (Sensitive) | 500 ng/mL (Standard) |
|---|---|---|
| Light (1–2 drinks) | 24–36 hours | 12–24 hours |
| Moderate (3–5 drinks) | 36–60 hours | 24–36 hours |
| Heavy (6+ drinks) | 60–80 hours | 36–60 hours |
Why Use This ETG Calculator?
ETG elimination varies from person to person, depending on hydration, health, metabolism, and drinking habits. This calculator gives a realistic estimate based on research-backed average data — not just guesses. It’s ideal for people who want to understand detection timing for legal or personal reasons.
Tips for More Accurate ETG Results
- Use the 100 ng option for sensitive or probation tests.
- Be honest about drink quantity and body weight for reliable results.
- Stay hydrated — dehydration can delay ETG elimination.
ETG Elimination FAQs
1. How long does ETG stay after one drink?
Usually around 24–36 hours for 100 ng cutoff tests and up to 24 hours for 500 ng tests.
2. Can I pass an ETG test after 48 hours?
If you consumed a small amount of alcohol, most people clear ETG within 48 hours, but heavy drinking can extend detection beyond 60 hours.
3. Can mouthwash or sanitizer cause a positive result?
Yes, alcohol-based hygiene products can cause low-level positives in very sensitive 100 ng tests.
4. Is this ETG calculator medically accurate?
No tool can replace lab analysis, but this calculator uses conservative scientific averages for realistic estimates.
