Can You Pass an ETG Test in 48 Hours?
Many people wonder: “Can I pass an ETG test in 48 hours after drinking?” The answer depends on several key factors — how much alcohol you consumed, your body’s metabolism, and the ETG test cutoff level being used. This guide explains realistic ETG detection times, alcohol elimination rates, and how to use an ETG Calculator to estimate your results.
What Is an ETG Test?
The ETG (Ethyl Glucuronide) test detects alcohol use by measuring ETG, a byproduct of ethanol metabolism. Unlike a breathalyzer, which only shows current impairment, ETG testing identifies alcohol consumption up to several days after drinking. It’s often used in probation, workplace, and addiction recovery programs.
Can You Pass an ETG Test in 48 Hours?
For most light to moderate drinkers, ETG may drop below detectable levels within 36–60 hours. However, if you consumed multiple drinks or have a slow metabolism, ETG can still be detectable at the 48-hour mark — especially in tests with a 100 ng/mL cutoff.
ETG Detection Time Table (Realistic)
Here’s a general reference table showing average ETG detection durations by drinking level and test cutoff:
| Drinking Level | Approx. ETG (ng/mL) | 100 ng/mL Cutoff | 500 ng/mL Cutoff |
|---|---|---|---|
| 1–2 drinks (Light) | 200–800 | 18–30 hours | 12–24 hours |
| 3–5 drinks (Moderate) | 800–3000 | 30–54 hours | 24–40 hours |
| 6+ drinks (Heavy) | 3000–9000+ | 60–80 hours | 48–72 hours |
Based on this data, you might pass a 500 ng/mL ETG test within 48 hours after light or moderate drinking, but not necessarily a 100 ng/mL test.
Factors Affecting ETG Elimination
- Amount of alcohol consumed: More drinks produce more ETG, extending detection time.
- Hydration: Staying hydrated may slightly lower ETG concentration but doesn’t eliminate it.
- Metabolism & body weight: Faster metabolism = shorter detection window.
- Liver function: A healthy liver clears alcohol more efficiently.
- Test sensitivity: 100 ng/mL cutoff tests detect alcohol for longer than 500 ng/mL tests.

Ways to Improve ETG Test Outcomes (Safe)
- Stop drinking immediately and allow time for ETG to clear naturally.
- Drink water to support healthy elimination.
- Eat balanced meals to boost metabolism.
- Avoid alcohol-based hygiene products before testing.
ETG Test FAQs
Can ETG Be Detected After 48 Hours?
Yes, especially for heavier drinking or sensitive 100 ng/mL tests. Light drinkers may clear it sooner.
Does Hydration or Exercise Reduce ETG Faster?
It helps metabolism slightly, but ETG still requires time to leave your body fully.
What Is the Best Way to Estimate ETG Results?
Use an Advanced ETG Calculator for a personalized prediction.
Final Thoughts
Whether you can pass an ETG test in 48 hours depends on alcohol intake, metabolism, and test sensitivity. For accurate estimates, use an to visualize your ETG levels over time. While moderate drinkers might pass a 500 ng/mL test in 48 hours, those using a 100 ng/mL test should expect a longer detection window.
