The ETG Level Calculator is a simple yet powerful online tool designed to help users quickly determine whether their Ethyl Glucuronide (ETG) levels fall above or below a given threshold. ETG testing is widely used to detect alcohol consumption through urine, hair, or blood tests. Knowing your ETG level compared to a specific threshold can be crucial for health monitoring, workplace testing, or compliance with sobriety programs.
This calculator allows you to input your ETG test value and the testing threshold to instantly get a result showing whether your level is “Above Threshold” or “Below Threshold.” It’s quick, user-friendly, and accurate.
ETG Level Calculator
What Is ETG and Why It Matters
Ethyl Glucuronide (ETG) is a direct metabolite of ethanol (alcohol). Unlike standard alcohol tests that detect recent drinking, ETG testing can detect alcohol use for up to 80 hours after consumption — depending on the test method and individual metabolism.
Healthcare providers, probation officers, and recovery programs often use ETG tests to ensure sobriety. Understanding your ETG levels helps:
- Monitor alcohol abstinence.
- Assess compliance in treatment or rehabilitation.
- Verify alcohol avoidance in professional or legal contexts.
About the ETG Level Calculator
The ETG Level Calculator simplifies ETG interpretation. It helps you compare your ETG test value (in ng/mL) against a known threshold value to quickly determine your status.
- If your ETG value is greater than or equal to the threshold, the result shows “Above Threshold.”
- If your ETG value is less than the threshold, the result shows “Below Threshold.”
This calculation is vital because ETG test thresholds vary by lab or institution. Common thresholds include 100 ng/mL, 500 ng/mL, or 1000 ng/mL, depending on the sensitivity of the test.
How to Use the ETG Level Calculator
Using the ETG calculator is very simple. Follow these steps:
- Enter Your ETG Value
Input your test result (e.g., 350 ng/mL) in the ETG Value field. - Enter the Threshold Value
Provide the threshold used by your testing laboratory (e.g., 500 ng/mL). - Click “Calculate”
The calculator instantly determines whether your ETG level is above or below the threshold and shows the difference in ng/mL. - View Your Result
- Status: Displays “Above Threshold” or “Below Threshold.”
- Difference: Shows how much your result differs from the threshold.
- Click “Reset” to start over.
Example Calculation
Let’s say you took an ETG urine test and received a result of 650 ng/mL, and your testing threshold is 500 ng/mL.
- ETG Value: 650
- Threshold: 500
- Difference: 150 ng/mL
- Status: Above Threshold
In this case, the calculator shows that your ETG level is 150 ng/mL above the limit, meaning alcohol use was likely detected.
If your ETG value were 300 ng/mL with a threshold of 500 ng/mL, the result would be:
- Difference: -200 ng/mL
- Status: Below Threshold
That would indicate no detectable alcohol consumption above the set limit.

When to Use the ETG Level Calculator
You can use the calculator when:
- You’ve received an ETG test result and want to interpret it.
- You’re in an alcohol recovery program and tracking progress.
- You want to understand test sensitivity or differences between labs.
- You’re a health professional monitoring ETG test data.
Important Notes
- The ETG Level Calculator does not replace laboratory interpretation or professional advice.
- ETG results can be influenced by individual metabolism, hydration, time since drinking, and lab sensitivity.
- Always verify thresholds with your testing facility or healthcare provider.
Understanding ETG Test Thresholds
ETG thresholds vary depending on the purpose:
| Type of Test | Common Threshold | Detection Window |
|---|---|---|
| Low-sensitivity | 100 ng/mL | Up to 80 hours |
| Moderate | 500 ng/mL | 48–72 hours |
| High-sensitivity | 1000 ng/mL | 24–48 hours |
For most recovery or compliance programs, 500 ng/mL is a standard cutoff.
Why ETG Testing Is Reliable
ETG testing is preferred because:
- It detects alcohol metabolites rather than ethanol itself.
- It remains in the system longer than alcohol.
- It minimizes false negatives caused by timing or dilution.
However, incidental exposure (like using hand sanitizer or mouthwash) can sometimes cause low-level ETG positives. Always consult your testing authority if unsure.
20 Frequently Asked Questions (FAQs) About the ETG Level Calculator
1. What does ETG mean?
ETG stands for Ethyl Glucuronide, a byproduct formed when alcohol is metabolized in the body.
2. What is the ETG Level Calculator used for?
It helps determine whether your ETG test result is above or below a specific threshold.
3. How accurate is the ETG calculator?
It’s 100% accurate mathematically — results depend on the accuracy of the data you enter.
4. What unit does the ETG calculator use?
All ETG levels are measured in nanograms per milliliter (ng/mL).
5. What is a typical ETG threshold?
Common thresholds include 100, 500, or 1000 ng/mL.
6. How do I know if I passed an ETG test?
If your ETG value is below the threshold, you have likely passed.
7. Can I use the calculator for hair ETG tests?
Yes, as long as you enter the correct units and threshold value.
8. Is ETG testing the same as alcohol breath testing?
No. Breath tests detect current alcohol; ETG detects recent alcohol use over a longer period.
9. What happens if my ETG is just slightly above the threshold?
It means alcohol metabolites are still present; discuss with your provider.
10. Does hydration affect ETG levels?
Yes, excessive water intake can dilute urine and reduce ETG concentration.
11. Can non-drinkers test positive for ETG?
Rarely. Some products containing alcohol (mouthwash, sanitizer) can cause low ETG levels.
12. What does “Above Threshold” mean?
It indicates your ETG result is higher than the cutoff, suggesting alcohol exposure.
13. What does “Below Threshold” mean?
It means your ETG level is lower than the threshold, typically a negative result.
14. Can ETG levels show how much alcohol was consumed?
Not exactly. ETG only indicates presence, not quantity.
15. How long can ETG remain detectable?
Up to 80 hours after drinking, depending on metabolism and test type.
16. Can I reset the calculator easily?
Yes — click the “Reset” button to clear all fields instantly.
17. Is the ETG calculator free to use?
Yes, it’s completely free and requires no login or signup.
18. Do I need to install any software?
No, it’s a web-based tool that runs directly in your browser.
19. Can I use it on my phone?
Absolutely! It’s fully responsive and mobile-friendly.
20. Is my data stored when I use this tool?
No — all calculations happen locally in your browser, keeping your data private.
