How Accurate is an ETG Calculator?

An ETG Calculator gives an estimate, not a guaranteed result. The accuracy depends on factors like:

ETG Calculator Formula

Here’s a simple method most ETG Calculators use to estimate detection time:

ETG Calculator Formula

1. Peak ETG Level:

\[ \text{Peak ETG (ng/mL)} = \text{Number of Standard Drinks} \times 500 – 1500 \]

2. ETG Elimination Rate:

\[ \text{ETG Elimination Rate} \approx 150 \ \text{ng/mL per hour} \]

3. Current ETG Level:

\[ \text{Current ETG} = \text{Peak ETG} – (\text{Elimination Rate} \times \text{Hours Since Last Drink}) \]

4. Time Until ETG is Undetectable:

\[ \text{Time to Clear (hours)} = \frac{\text{Peak ETG} – \text{Detection Threshold}}{\text{Elimination Rate}} \]

Note: Detection Threshold is usually 500 ng/mL. Adjust calculations for body weight, gender, and hydration level.
