Disclaimer | EtG Calculator Hub
Last Updated: [10 August 2026]
1. General Disclaimer
The information, tools, and calculator results available on EtG Calculator Hub (https://etgcalculatorhub.com/) are provided for general educational and informational purposes only.
EtG Calculator Hub is not a medical laboratory, healthcare provider, law firm, government agency, probation service, or testing authority. Nothing on this website should be treated as professional medical, legal, or testing advice.
2. Calculator Estimates
Our calculators, including the EtG Calculator, Advanced EtG Calculator, and ETG 100 ng/mL Calculator, generate estimates based on mathematical models and the information users enter.
Please understand that:
- Calculator results are not measurements of blood or urine.
- Calculator results are not laboratory test results.
- Results are not guaranteed to match an individual’s actual EtG concentration.
- Individual biological variation can cause real-world results to differ substantially from a model estimate.
- A calculated value should never be interpreted as a confirmed laboratory result.
Our tools are designed to help users explore general concepts — not to determine or predict an individual outcome.
3. EtG and Urine Testing
Ethyl glucuronide (EtG) is a metabolite associated with ethanol exposure. Urine EtG testing involves the laboratory analysis of an actual biological specimen.
Real-world EtG results can vary due to numerous factors, including:
- Amount and pattern of alcohol exposure
- Time since drinking
- Individual metabolism
- Urine concentration and dilution
- Kidney function
- Testing methodology
- Laboratory procedures
- Cutoff concentration used
Our calculators cannot account for every individual factor that may influence a real laboratory result.
4. Cutoff Values
EtG testing may use different cutoff concentrations depending on the laboratory or testing program. A cutoff is a threshold used by a testing method — it is not a guaranteed detection timeline.
The ETG 100 ng/mL Calculator is specifically modeled around a 100 ng/mL cutoff assumption. This calculator cannot determine whether an individual will produce a specific result on an actual laboratory test.
5. No Guarantee of Test Results
EtG Calculator Hub cannot and does not guarantee:
- A negative result
- A positive result
- A specific urine EtG concentration
- A specific detection time
- A specific laboratory outcome
- Compliance with any testing requirement
Our tools are not designed or intended to help users time alcohol consumption around a test.
6. BAC and Alcohol Safety
Where our calculators display blood alcohol concentration (BAC) estimates, these figures are also mathematical estimates, not measurements. BAC estimates should never be used to determine whether it is safe to drive, operate machinery, or engage in any activity requiring sobriety.
Never rely on a calculator to decide whether you are safe to drive after drinking. If there is any uncertainty, do not drive.
7. No Medical Advice
Content on EtG Calculator Hub is not intended to diagnose, treat, cure, or prevent any medical condition. If you have questions about alcohol use, health, or testing, please consult an appropriately qualified healthcare professional.
8. No Legal, Employment, Probation, or Compliance Advice
EtG Calculator Hub does not provide legal advice. Calculator results should not be used to determine compliance with:
- Court requirements
- Probation or parole conditions
- Employment testing programs
- Workplace policies
- Custody arrangements
- Treatment-program requirements
- Any other testing requirement
If you are subject to any of the above, please consult the appropriate qualified professional or testing authority directly.
9. Individual Variation
Two people with similar drinking histories can receive very different laboratory results. Population-level mathematical models cannot fully reproduce any one individual’s physiology, metabolism, urine concentration, kidney function, or the specific conditions of a laboratory test.
10. Third-Party Information and Links
Our website may reference or link to external sources for informational purposes. EtG Calculator Hub does not control these third-party websites and is not responsible for their content, accuracy, availability, or privacy practices.
11. Accuracy and Updates
We aim to provide accurate, research-informed information, but we cannot guarantee that every piece of content is complete, current, or error-free. Calculators, formulas, assumptions, and reference content may be updated over time as our understanding evolves.
12. Limitation of Liability
To the extent permitted by applicable law, EtG Calculator Hub and its operators are not responsible for any losses, damages, decisions, or consequences arising from reliance on website content or calculator results. Use of this website and its tools is at your own discretion and risk.
13. Use of the Website
Users are responsible for how they interpret and use the information provided on EtG Calculator Hub. Our calculators should be treated as educational modeling tools intended to support general understanding — not as authoritative testing instruments.
14. When You Need a Real Test Result
If you need to know your actual EtG concentration or your status regarding a laboratory testing requirement, only an appropriately performed laboratory test of an actual specimen can provide that information. EtG Calculator Hub does not offer, and will not provide, guidance on manipulating, avoiding, or defeating any form of testing.
