ETG 100 ng/mL Calculator – Estimate Your Urine ETG Levels Accurately
Welcome to our ETG 100 ng/mL Calculator – your professional tool to estimate urine ethyl glucuronide (ETG) levels after alcohol consumption. ETG testing is widely used to detect recent alcohol use in clinical, forensic, and workplace settings. Our calculator is designed to provide an accurate estimate of your ETG concentration, helping you understand whether your levels might exceed the commonly used 100 ng/mL detection threshold.
What is ETG and Why is it Important?
Ethyl glucuronide (ETG) is a direct metabolite of ethanol, formed in the liver when your body processes alcohol. Unlike alcohol itself, ETG remains in urine for a longer period, typically detectable up to 80 hours after drinking, depending on the amount of alcohol consumed, your metabolism, and hydration levels.
ETG testing is particularly important in:
- Clinical settings: Monitoring patients in alcohol treatment programs.
- Workplace testing: Ensuring employees remain alcohol-free in safety-sensitive roles.
- Legal and forensic cases: Confirming abstinence or recent alcohol consumption.
The 100 ng/mL threshold is commonly used as the cutoff for a positive ETG test in urine, which is why understanding your ETG levels can be valuable if you are monitoring alcohol intake.
How the ETG 100 ng/mL Calculator Works
Our ETG test calculator estimates your urine ETG concentration based on several key factors:
- Weight: Your body mass affects how alcohol is distributed and metabolized.
- Gender: Men and women metabolize alcohol differently due to variations in liver enzymes and body composition.
- Number of drinks: Each standard drink contains approximately 14 grams of pure ethanol.
- Time since last drink: Alcohol metabolizes at an average rate of 0.015–0.017 g/dL per hour, reducing ETG levels over time.
By combining these inputs, the calculator provides an estimated ETG concentration (ng/mL) and a risk assessment, showing whether your ETG is likely below or above 100 ng/mL.
Why Use an ETG Calculator?
Using an ETG test calculator has several advantages:
- Immediate results: Quickly estimate your urine ETG levels without waiting for lab tests.
- Better planning: Understand how long alcohol stays in your system before it can be detected in urine.
- Awareness: Helps individuals in alcohol recovery programs monitor their progress and maintain abstinence.
- Education: Learn how factors like weight, metabolism, and drinking volume affect ETG levels.
While our calculator provides an accurate estimate, it is important to remember that it does not replace laboratory testing. Individual metabolism and hydration can significantly affect ETG detection.

This color coding makes it easy to interpret results at a glance.
Understanding ETG Detection in Urine
ETG is considered one of the most reliable biomarkers for detecting alcohol use. Unlike blood alcohol content (BAC), which drops rapidly after drinking, ETG remains detectable for a longer period.
- Small amounts of alcohol: ETG can detect even minimal consumption, such as one drink, in some cases.
- Detection window: Generally, ETG remains detectable in urine for up to 3–4 days after drinking.
- Thresholds: Laboratories often use 100 ng/mL as the standard cutoff for a positive result, though some stricter tests may use 500 ng/mL for verification.
By understanding these factors, you can use our ETG 100 ng/mL calculator to estimate whether your ETG levels are likely to exceed the standard detection threshold.
Factors Affecting ETG Levels
Several factors can influence urine ETG levels:
- Alcohol Consumption: Higher amounts increase ETG levels proportionally.
- Body Weight and Gender: Larger body mass or male metabolism may reduce ETG concentration per unit of alcohol.
- Time Since Drinking: ETG decreases over time as alcohol is metabolized and excreted.
- Hydration Status: Diluted urine can reduce ETG concentration, potentially lowering detection.
- Metabolism Rate: Genetic variations in liver enzymes can speed up or slow down alcohol processing.
Our calculator accounts for weight, gender, drinks, and hours since last drink, providing a reliable estimate under standard assumptions.
Why 100 ng/mL is the Standard Threshold
Most urine ETG tests use 100 ng/mL as the cutoff for a positive result because:
- It is sensitive enough to detect recent alcohol use.
- It reduces false positives from incidental exposure (like hand sanitizer or mouthwash).
- It aligns with clinical and forensic best practices.
Using the ETG calculator, you can see how your drinking behavior aligns with this threshold, helping you make informed decisions.

Tips for Accurate ETG Estimation
To ensure the calculator provides a more accurate estimate:
- Use standard drink units for input. One standard drink = 14 grams of pure ethanol.
- Avoid assuming uniform metabolism; individual variations exist.
- Input your exact weight in kilograms for more accurate results.
- Time since last drink is critical: ETG decreases gradually as alcohol is metabolized.
- Understand that hydration can dilute ETG, lowering urine concentration temporarily.
Remember, our ETG calculator provides an estimate, not a laboratory-confirmed result. For critical decisions, always rely on official ETG testing.
Who Should Use This ETG Calculator?
This ETG 100 ng/mL calculator is useful for:
- Individuals in alcohol recovery programs monitoring abstinence.
- Employers or occupational health programs educating staff on alcohol detection.
- Healthcare professionals explaining ETG test results to patients.
- Anyone interested in learning how alcohol affects ETG levels over time.
It is simple, professional, and designed for educational purposes while maintaining accuracy within scientific limits.
Frequently Asked Questions (FAQ)
1. Can this calculator replace lab tests?
No. The calculator provides an estimate only. For legal or clinical purposes, always rely on urine ETG testing by certified labs.
2. How long does ETG stay detectable?
ETG can be detected for up to 80 hours after alcohol consumption, depending on the amount consumed, body weight, and metabolism.
3. Why is the threshold 100 ng/mL?
100 ng/mL is a standard cutoff that detects recent alcohol use while minimizing false positives from incidental alcohol exposure.
4. Does hydration affect ETG levels?
Yes, increased urine volume can dilute ETG, reducing its concentration.
5. Can I estimate ETG after one drink?
Yes, the calculator can provide an estimate, but small amounts may be close to or below the detection limit.
