Note: This calculator provides estimates only. Individual metabolism varies by ±40%. Not for medical or legal use.

The ETG Calculator estimates ethyl glucuronide (ETG) levels in your system based on drink consumption, body metrics, and time elapsed. This scientific tool helps predict alcohol detection window for workplace tests, legal compliance, and health management.

What Is It? - ETG Calculator

A computational model that:

  • Calculates ETG concentration (ng/mL)
  • Predicts detection windows (up to 80 hours)
  • Adjusts for gender/age metabolic differences

Key Formula

ETG = \frac{(Drinks × Alcohol_{grams} × 0.0022 × 10^6)}{Weight_{kg} × Hours} × Gender_{factor} × Age_{factor}

*Where:

  • Gender factor: Female 1.15 / Male 1.0
  • Age factor: 1 + (Age - 30) × 0.005*

How to Use

  1. Select drink type (beer/wine/liquor)
  2. Enter:
    • Number of drinks
    • Body weight (kg/lbs)
    • Hours since consumption
  3. View results:
    • Real-time ETG concentration
    • Metabolic curve visualization
    • Risk classification (Normal/Caution/High Risk)

FAQs

Q: How accurate is this calculator?
A: Provides estimates within ±40% variability due to individual metabolism differences.

Q: Why does gender affect results?
A: Women typically have lower water content and slower alcohol dehydrogenase enzyme activity.

Q: What’s the 500 ng/mL cutoff?
A: Common workplace testing threshold, though some labs use 100 ng/mL for stricter screening.

Terminology

  • ETG (Ethyl Glucuronide): Direct alcohol biomarker detectable longer than BAC
  • PEth: Complementary biomarker for chronic alcohol use
  • Window of Detection: 24-80 hours depending on test sensitivity
  • NG/ML: Nanograms per milliliter (standard ETG unit)
