What is ETG (Ethyl Glucuronide)?

Ethyl Glucuronide (ETG) is a direct metabolite of alcohol (ethanol). When you consume alcohol, your body processes it and produces ETG as a byproduct. Unlike alcohol itself, which may clear from your system relatively quickly, ETG can be detected for a longer period after alcohol consumption.

ETG testing has become increasingly common in various settings, including substance abuse programs, probation monitoring, workplace testing, and healthcare scenarios where alcohol abstinence needs to be verified.

How Long Does ETG Stay in Your System?

The detection window for ETG varies based on several factors:

  • Amount of alcohol consumed: Higher consumption generally leads to longer detection times.
  • Frequency of drinking: Regular drinkers may have longer detection periods due to accumulated ETG.
  • Individual metabolism: Factors like age, weight, gender, and liver function affect how quickly your body processes alcohol.
  • Hydration level: Being well-hydrated may help your body eliminate ETG more efficiently.
  • Test sensitivity: Different tests have different cutoff levels for detecting ETG.

Generally, ETG can be detected in urine for approximately:

  • Light drinking (1-2 drinks): 24-48 hours
  • Moderate drinking (3-5 drinks): 48-72 hours
  • Heavy drinking (6+ drinks): 72-80+ hours

ETG Testing Methods

ETG can be detected through various testing methods:

Urine Testing

The most common method for ETG detection. Urine tests can detect ETG for up to 80 hours after heavy alcohol consumption.

Hair Testing

Hair tests can detect ETG for a much longer period, potentially up to 90 days, depending on hair length and growth rate.

Blood Testing

Blood tests have a shorter detection window, typically 12-24 hours, and are less commonly used for ETG specifically.

Saliva Testing

Saliva tests are less common for ETG and have a shorter detection window of approximately 12-24 hours.

Factors That Can Affect ETG Test Results

Several factors can influence ETG test results:

  • Incidental alcohol exposure: Some products like mouthwash, hand sanitizers, and certain foods contain small amounts of alcohol that could potentially trigger a positive ETG test.
  • Medications: Some medications may interfere with ETG testing or contain alcohol as an ingredient.
  • Test sensitivity: Different tests have different cutoff levels, affecting what constitutes a "positive" result.
  • Sample contamination: Improper handling of test samples can lead to false results.
  • Individual metabolism: Variations in how individuals process alcohol can affect ETG production and elimination.

How to Use This Calculator

Our ETG Calculator provides an estimate of how long ETG may be detectable in your system:

  1. Enter the number of standard drinks consumed.
  2. Specify when you finished drinking (date and time).
  3. Input your personal details (weight, gender, etc.).
  4. Click "Calculate" to receive an estimated detection window.

Important Disclaimer: This calculator provides estimates based on general patterns and research. Individual results may vary significantly. The calculator should not be used to determine if you will pass an ETG test, and should not be used to make decisions that could have legal or health consequences.

Standard Drink Equivalents

A "standard drink" contains about 14 grams (0.6 ounces) of pure alcohol. Here's how that translates to common beverages:

Beer (5%)

12 oz (355 ml)

Wine (12%)

5 oz (148 ml)

Spirits (40%)

1.5 oz (44 ml)

Malt Liquor (7%)

8-9 oz (237-266 ml)
