ETG Alcohol Urine Test Calculator
Are you curious about how long alcohol may be detected in your urine? Our ETG Alcohol Urine Test Calculator provides an educational, medically informed estimate of your EtG (Ethyl Glucuronide) levels based on your alcohol intake, body weight, sex, and time since your last drink. This tool is designed for educational purposes only and is not a replacement for professional laboratory testing.
What is an ETG Alcohol Test?
The EtG (Ethyl Glucuronide) urine test is a sensitive biomarker used in toxicology to detect alcohol consumption. Unlike standard breath or blood alcohol tests, EtG can detect alcohol use up to 80 hours after consumption. EtG forms in the liver when your body metabolizes ethanol and is then excreted in urine.
This test is widely used in:
- Workplace alcohol testing
- Rehabilitation and recovery programs
- Medical and clinical monitoring
Knowing your potential EtG levels can help you understand how long alcohol may remain detectable in your system, but individual results vary depending on metabolism, hydration, liver function, and laboratory methods.
How Does the ETG Alcohol Urine Test Calculator Work?
Our calculator provides an estimate based on:
- Number of drinks consumed – Each standard drink contains approximately 14 grams of pure alcohol.
- Body weight – Heavier individuals generally metabolize alcohol slightly faster.
- Biological sex – Differences in body water and metabolism between males and females are accounted for.
- Hours since last drink – The longer the time, the lower the EtG levels.
- EtG cutoff level – Common lab cutoffs range from 100 ng/mL (very strict) to 500 ng/mL (lenient).
The calculator generates:
- Estimated EtG range (ng/mL)
- Test cutoff comparison
- Risk level (Likely Pass, Borderline, Likely Fail)
- Estimated detection window remaining
This gives a quick, visual, and medically safe estimate of your alcohol detection timeline.
Why Use an ETG Urine Test Calculator?
While laboratory testing provides definitive results, an online calculator is a useful educational tool to:
- Plan for recovery or abstinence periods
- Understand how your body metabolizes alcohol
- Estimate your detection window for clinical monitoring
- Make informed decisions in rehabilitation or workplace compliance
Important: This tool is not a replacement for lab testing and cannot provide medical or legal guarantees. Individual metabolism, hydration, medications, and liver health all affect EtG levels.
Understanding ETG Cutoff Levels
Different labs may use varying cutoff levels to determine positive or negative results:
| Cutoff Level (ng/mL) | Typical Usage | Interpretation |
|---|---|---|
| 100 | Very strict | Likely positive with minimal alcohol consumption |
| 300 | Common | Standard detection threshold in many labs |
| 500 | Lenient | Less sensitive, may detect only heavier drinking |
Your risk level in the calculator reflects these cutoffs, helping you understand whether your estimated EtG is above or below common lab thresholds.
Factors Affecting ETG Detection
EtG levels are influenced by multiple factors, including:
- Metabolism rate – Faster metabolism can lower EtG levels more quickly.
- Body hydration – Drinking water dilutes urine and may slightly affect concentration.
- Frequency and quantity of alcohol consumption – Heavy or repeated drinking may increase detection window.
- Medications and liver function – Certain medications or liver conditions can alter alcohol metabolism.
- Lab assay sensitivity – Different labs may have varying cutoff standards and detection methods.
Because of these variables, our calculator provides estimates only. Always consult a medical professional for clinical interpretation.
How to Use the ETG Alcohol Test Calculator
- Enter the number of drinks you consumed.
- Input your body weight in kilograms.
- Select your biological sex (male/female).
- Enter hours since your last drink.
- Choose your EtG cutoff level based on lab standards.
- Click “Estimate EtG” to see your risk level and detection window.
The calculator will generate:
- Estimated EtG range (ng/mL)
- Comparison with chosen cutoff
- Risk level (green/orange/red indicator)
- Estimated detection window remaining
- A visual chart showing EtG levels over time

Limitations and Safety Notes
- This tool does not provide legal or clinical guarantees
- Results are estimates, not definitive lab results
- Factors like metabolism, hydration, and liver function may affect actual EtG levels
- Medical consultation is recommended for health decisions
Why ETG Testing Matters
EtG testing is a gold standard for monitoring alcohol abstinence. Understanding your estimated detection window helps:
- Patients in rehabilitation programs track progress
- Employers ensure workplace safety compliance
- Individuals make informed health decisions
Using our calculator helps raise awareness and educate users about alcohol metabolism without replacing clinical testing.
