How Accurate Is ETG Alcohol Testing?

ETG alcohol testing is widely used because it can identify alcohol metabolites that remain detectable after alcohol is no longer measurable in breath. When specimens are collected and processed according to established laboratory procedures, ETG testing provides a reliable method for monitoring recent alcohol consumption.

What Makes ETG Testing Reliable?

ETG is produced only after alcohol enters the body.

This makes ETG testing different from methods that measure current alcohol concentration.
