Understanding ETG Levels & Detection Times
ETG (ethyl glucuronide) is a direct metabolite of alcohol, measurable in urine for up to several days after drinking. Our ETG Level Calculator estimates how your drinking patterns, body weight, and gender influence ETG levels and detection windows.
How ETG Is Produced
After alcohol consumption, the liver metabolizes ethanol and produces ETG. ETG remains in the bloodstream and urine long after alcohol effects wear off, making it a reliable biomarker for recent alcohol use. Factors like body weight, metabolic rate, gender, and hydration influence the measured ETG level.
Using the ETG Calculator
- Enter your number of drinks consumed or expected.
- Input body weight and select gender for a more personalized estimate.
- Choose the cutoff sensitivity of the test (100, 200, or 500 ng/mL).
- Press “Calculate” to see your estimated ETG level and detectability chart.
Factors Affecting ETG Levels
- Amount of alcohol: More drinks = higher ETG peak and longer detection.
- Body composition & weight: Lower weight often means higher concentration.
- Gender: Females often have slightly higher detectable ETG.
- Hydration: Dilution can lower urine ETG concentration.
- Metabolism & liver function: Faster metabolism reduces detectable hours.
Typical ETG Detection Cutoffs
- 100 ng/mL — high sensitivity, detects low alcohol exposure.
- 200 ng/mL — moderate sensitivity, common for workplace testing.
- 500 ng/mL — low sensitivity, standard in probation monitoring.
Important Notes
This ETG Level Calculator provides educational and illustrative estimates. Actual ETG concentrations depend on numerous physiological factors, and only laboratory testing can confirm precise results. Use this tool to understand trends, detectability windows, and for learning purposes.
