ETG Detection Time Calculator




Wondering how long alcohol byproducts (ETG) stay detectable? Our ETG Detection Time Calculator gives you a fast, science-backed estimate based on your drinking habits, metabolism, and body weight. Simply enter your details to see how long ETG might appear in tests—whether for personal awareness or preparation. While results vary by individual, this tool offers a reliable baseline understanding of detection windows. Quick, confidential, and no medical jargon—just clear insights to help you plan

How It Works

ETG (ethyl glucuronide) is a metabolite that can indicate alcohol consumption. This calculator estimates detection time using three key factors:

  1. Number of Standard Drinks
  • Enter the total drinks consumed (1 standard drink = 14g pure alcohol).
  • Example: 2 beers, 1 glass of wine, or 1 shot of liquor each count as ~1 drink.
  1. Hours Since Last Drink
  • How long it’s been since your final drink.
  • ETG typically remains detectable for 24–80 hours after drinking.
  1. Body Weight (kg)
  • Metabolism varies by weight—lighter individuals may process alcohol more slowly.

Why Use This Tool?

  • Fast & Confidential: Get instant results without sharing personal data.
  • Science-Based: Uses widely accepted formulas for ETG detection windows.
  • Practical Guidance: Helps plan for tests or personal awareness.

⚠️ Note: This is an estimate only. Actual detection times vary based on hydration, liver health, and other factors. Consult a medical professional for critical decisions.

Frequently Asked Questions

Q: How accurate is this calculator?
A: It provides a general estimate based on population averages. Individual results may differ.

Q: Can ETG be detected after 80 hours?
A: Rarely. Heavy drinking might extend detection slightly, but 80 hours is the typical upper limit.

Q: Does water or exercise help flush out ETG?
A: No. ETG is eliminated by your liver—hydration and exercise have minimal impact.
