Does testing for etg in system always test up to 80 hours or does it sometimes test up to 72 hours?

ETG (ethyl glucuronide) testing can vary in its detection window depending on several factors, including the individual's metabolism, the amount of alcohol consumed, and the type of test used. Generally, ETG can be detected in urine for up to 80 hours after alcohol consumption, but some tests may have a shorter detection window of around 72 hours. It's important to consider that individual results may differ based on personal circumstances.
