ETG Elimination Time Calculator
Estimate how long Ethyl Glucuronide (ETG) may remain detectable in your urine. This ETG elimination calculator gives a realistic detection window for 100 ng/mL (sensitive) and 500 ng/mL (standard) cutoffs.
How this ETG Elimination Calculator works
This calculator uses an evidence-based approximation to convert your drinking details into a detection-time range. It factors:
- Number of standard drinks
- Hours since your last drink
- Body weight
- Gender (broad metabolic differences)
- Test cutoff sensitivity (100 ng vs 500 ng)
Average detection ranges (guide)
| Drinking level | 100 ng cutoff | 500 ng cutoff |
|---|---|---|
| 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 |
Tips to improve accuracy
- Enter accurate body weight and exact drink count (standard drink = 14 g ethanol).
- Use 100 ng if you suspect a sensitive lab/probation test.
- Remember: this gives an estimate. Only lab testing is definitive.
Article: Calculate ETG Elimination Time — Quick Explanation
ETG elimination time is the period it takes for ETG to fall below a lab’s detection cutoff. ETG forms after alcohol metabolism and clears slower than blood alcohol. The calculator below estimates the likely window when ETG remains detectable in urine.
Short method (manual)
As a quick rule: multiply drinks × 8 hours as a baseline, then adjust for gender, weight and cutoff. Our tool automates those adjustments and returns a conservative range (min–max hours).

Frequently Asked Questions
How long does ETG stay after one drink?
Typically ~24–36 hours for a single drink at the 100 ng cutoff; shorter for 500 ng.
Can I pass an ETG test after 48 hours?
Possibly if you drank little; heavy drinking can still be detectable beyond 48 hours.
Do hygiene products cause false positives?
Yes — mouthwash or sanitizer can affect sensitive 100 ng tests. Explain incidental exposure to lab personnel if needed.
