1. What is ETG Testing?

Ethyl glucuronide (ETG) is a direct metabolite of ethanol used as a biomarker for alcohol consumption. ETG testing can detect alcohol use even after ethanol is no longer measurable in blood or urine.

2. How Does the Calculator Work?

The calculator estimates ETG clearance based on:

Factors considered:

• Alcohol dose consumed (in standard drinks)
• Body weight (kg)
• Time since last drink (hours)
• Individual metabolism variations

3. Importance of ETG Testing

Details: ETG testing is crucial for monitoring abstinence in alcohol recovery programs, workplace testing, and legal situations. It can detect alcohol consumption for up to 80 hours after drinking.

4. Using the Calculator

Tips: Enter the number of standard drinks consumed, your body weight in kg, and time since last drink. The calculator provides an estimate of current ETG levels and detection window.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is ETG testing?
A: ETG testing is highly sensitive but can be affected by factors like hydration, liver function, and individual metabolism.

Q2: What's the cutoff level for a positive ETG test?
A: Common cutoff is 100 ng/mL for initial testing and 500 ng/mL for confirmation, but this varies by testing program.

Q3: Can hand sanitizers cause positive ETG tests?
A: Extensive use of alcohol-based products might lead to low-level positives, but not typically above confirmation cutoffs.

Q4: How long is ETG detectable?
A: Typically 24-80 hours depending on amount consumed, but heavy drinking may be detectable longer.

Q5: Does this calculator account for individual variations?
A: No, this provides general estimates. Actual clearance times vary based on many individual factors.
