ETG Calculator Online

Our ETG Calculator is a free ETG urine test calculator that estimates Ethyl Glucuronide levels in urine and predicts your detection window. Designed for educational purposes, it helps users understand how alcohol may be detected in urine based on number of drinks, drink size, body weight, gender, and hours since the last drink.

How the ETG Calculator Works

The ETG Calculator estimates your urine ETG concentration using your inputs. It:

  • Converts standard drinks into grams of alcohol
  • Models alcohol absorption
  • Applies average elimination rates to predict ETG excretion

The tool also estimates approximate ETG elimination time, showing when levels may fall below selected cutoff thresholds.

Results include:

  1. Estimated ETG concentration
  2. Approximate time until ETG falls below common cutoffs
  3. Predicted ETG levels at cutoff times

Note: Results are estimates only. Individual metabolism and lab methods may vary.

ETG Detection Window (100, 200 & 500 ng/mL)

Cutoff LevelLight Drinking (1–2 drinks)Moderate Drinking (3–6 drinks)Heavy Drinking (7+ drinks)
100 ng/mL24–48 hrs48–100 hrs72–130 hrs
200 ng/mL18–36 hrs36–80 hrs48–100 hrs
500 ng/mL12–24 hrs24–48 hrs48–72 hrs

The table above shows estimated ETG detection time after drinking based on different cutoff levels and drinking patterns.

Factors Affecting ETG Levels

  • Alcohol consumption amount and frequency
  • Body weight and gender
  • Hydration levels
  • Metabolism and liver function
  • Type of drinks
  • Individual differences in ETG half-life

Why Use Our ETG Calculator

  • Estimate ETG levels before testing
  • Understand detection windows
  • Educational tool for sobriety tracking
  • Helps plan alcohol abstinence monitoring

ETG vs PEth Testing

  • ETG: Short-term alcohol use (up to 3–5 days, urine test)
  • PEth: Long-term alcohol use (2–4 weeks, blood test)

Use the ETG Calculator for short-term detection and the PEth Level Calculator for long-term monitoring.

FAQ | ETG Test Calculator

Depends on number of drinks, cutoff level, and metabolism. Light drinkers may test negative; heavy drinkers may remain positive.

ETG (Ethyl Glucuronide) is a metabolite formed after alcohol consumption, detectable in urine long after alcohol leaves the bloodstream. ETG testing is commonly used as an alcohol urine test to detect recent drinking.

It provides educational estimates. Only lab urine tests confirm actual ETG levels.

Common cutoffs: 100 ng/mL (sensitive), 200 ng/mL (moderate), 500 ng/mL (standard/probation).

Yes. Hand sanitizers, mouthwash, fermented foods, and some medications may trigger positive ETG results.
