ETG Calculator Dekho – Alcohol Detection And Awareness
Wondering how long alcohol stays in your system? An ETG Calculator is a simple tool to estimate how long alcohol metabolites, specifically Ethyl Glucuronide (ETG), remain detectable in urine. Unlike standard BAC (Blood Alcohol Concentration) tests, ETG tests can detect alcohol for up to 80 hours after drinking. This makes the ETG Helth Calculator useful for recovery tracking, sobriety monitoring, and alcohol awareness.
Why Use an ETG Calculator?
- Check Detection Time: Quickly estimate how long ETG may remain in your urine.
- Plan Testing or Recovery: Useful if you are preparing for an alcohol urine test or tracking sobriety.
- Personal Awareness: Understand how drinking habits, hydration, weight, and gender influence detection.

How Accurate is an ETG Calculator?
An ETG Calculator gives an estimate, not a guaranteed result. The accuracy depends on factors like:
- Body Weight: Heavier individuals may metabolize alcohol differently.
- Gender: Men and women metabolize alcohol at slightly different rates.
- Hydration Level: Being hydrated can reduce ETG concentration in urine.
- Number of Drinks & Timing: More drinks or shorter time since the last drink increase detection.

ETG Calculator Formula
Here’s a simple method most ETG Calculators use to estimate detection time:
ETG Calculator Formula
1. Peak ETG Level:
\[ \text{Peak ETG (ng/mL)} = \text{Number of Standard Drinks} \times 500 – 1500 \]
2. ETG Elimination Rate:
\[ \text{ETG Elimination Rate} \approx 150 \ \text{ng/mL per hour} \]
3. Current ETG Level:
\[ \text{Current ETG} = \text{Peak ETG} – (\text{Elimination Rate} \times \text{Hours Since Last Drink}) \]
4. Time Until ETG is Undetectable:
\[ \text{Time to Clear (hours)} = \frac{\text{Peak ETG} – \text{Detection Threshold}}{\text{Elimination Rate}} \]
Note: Detection Threshold is usually 500 ng/mL. Adjust calculations for body weight, gender, and hydration level.
- Detection Threshold: Usually 500 ng/mL for urine tests.
- This formula can be adjusted for weight, gender, and hydration level.
Example Calculation
Input | Value |
---|---|
Number of Drinks | 2 |
Hours Since Last Drink | 18.5 |
Body Weight | 70 kg |
Gender | Male |
Hydration | Normal |
Metric | Result | Description |
---|---|---|
Estimated Detection Window | 24.0 hours | ETG may be detectable in urine after your last drink |
Current Risk Status | Low | Your risk of testing positive is low |
Time Until ETG is No Longer Detectable | 5.5 hours | ETG expected to be undetectable after this time |
Note: For weight in lb, the same input produces slightly longer detection times due to conversion differences.
What is a Normal ETG Level?
- Undetectable: < 500 ng/mL (most tests consider this safe/negative).
- Moderate Detection: 500–1000 ng/mL (low to moderate risk of detection).
- High Detection: > 1000 ng/mL (high risk of testing positive).
ETG Date and Time Calculator for Alcohol Awareness
Using an ETG Calculator, you can:
- Estimate when ETG will no longer be detectable in urine.
- Track your alcohol metabolism over time.
- Plan tests or recovery schedules safely.
Example:
- 2 standard drinks, 18 hours since last drink, 70 kg body weight, male, normal hydration → Estimated detection window: ~24 hours, Time until ETG undetectable: ~5.5 hours.
People Also Ask (FAQs)
How long can ETG detect alcohol in urine?
Up to 80 hours, depending on drinking amount, body weight, gender, and hydration.
Is this ETG Calculator free?
Yes, completely free for personal use.
Can I use this for legal testing?
No. This is an estimate only. For legal or clinical testing, consult a professional.
How accurate is the ETG Calculator?
Accuracy varies per individual, but it gives a reliable estimate for personal awareness and recovery tracking.
What is considered a normal ETG level?
< 500 ng/mL is usually considered negative; higher values indicate the presence of alcohol metabolites.
