ETG Calculator Online | Free ETG Urine Test Calculator
Estimate your ETG (Ethyl Glucuronide) levels in urine and understand your alcohol detection window with our free online ETG Calculator. Designed for educational purposes, this tool helps you calculate ETG levels based on the number of drinks, drink size, body weight, gender, and hours since your last drink.
Whether you are monitoring sobriety, planning alcohol abstinence, or preparing for a urine alcohol test, this realistic ETG calculator provides an informative estimate of your current ETG concentration.
How the ETG Calculator Works
Our ETG calculator online works by analyzing your drinking data and estimating your urine ETG concentration. The tool uses the following steps:
- Converts standard drinks into grams of alcohol.
- Models alcohol absorption during drinking.
- Applies average elimination rates to predict ETG excretion.
- Estimates when ETG levels fall below common cutoff thresholds.
The results include:
- Estimated ETG concentration in urine.
- Approximate time until ETG falls below cutoff levels (100, 200, 500 ng/mL).
- Predicted ETG levels at cutoff times.
Note: Results are estimates. Individual metabolism, hydration, and lab methods can vary.
ETG Detection Window
Different ETG cutoff levels correspond to detection windows for light, moderate, and heavy drinking. The table below shows approximate detection times based on drinks consumed and cutoff levels:
| Cutoff Level | Light Drinking (1–2 drinks) | Moderate Drinking (3–6 drinks) | Heavy Drinking (7+ drinks) |
|---|---|---|---|
| 100 ng/mL | 24–48 hrs | 48–100 hrs | 72–130 hrs |
| 200 ng/mL | 18–36 hrs | 36–80 hrs | 48–100 hrs |
| 500 ng/mL | 12–24 hrs | 24–48 hrs | 48–72 hrs |
This ETG test calculator table helps visualize detection times and plan accordingly.
Factors Affecting ETG Levels
Several factors influence ETG concentrations in your urine:
- Amount and frequency of alcohol consumption.
- Body weight and gender.
- Hydration levels and fluid intake.
- Metabolism and liver function.
- Type of alcoholic drinks consumed.
- Individual differences in ETG half-life.
Understanding these factors improves the accuracy of your ETG level calculations and can help you interpret results realistically.
Why Use Our ETG Calculator
Our free ETG urine test calculator is designed for practical and educational use:
- Estimate your ETG levels before testing.
- Understand detection windows for different drinking patterns.
- Monitor sobriety or plan abstinence periods.
- Gain insights into how alcohol is metabolized and cleared.
By using this tool, you get a realistic view of your urine ETG levels without relying solely on lab testing.
ETG vs PEth Testing
It’s important to know the difference between short-term and long-term alcohol monitoring:
- ETG (Ethyl Glucuronide): Detects recent alcohol consumption in urine, up to 3–5 days.
- PEth (Phosphatidylethanol): Detects long-term alcohol consumption in blood, up to 2–4 weeks.
Use the ETG Calculator for short-term detection and the PEth Calculator for long-term monitoring. Try our PEth Calculator to understand cumulative alcohol intake.
How to Calculate ETG Levels
Calculating ETG levels involves:
- Entering the number of drinks consumed.
- Selecting drink size (standard 14 g alcohol).
- Adding body weight and gender.
- Entering hours since last drink.
The calculator then generates an estimated ETG concentration, elimination timeline, and detection probability.
