What is the lifespan of EtG?

Could you please elaborate on the lifespan of EtG, or ethyl glucuronide, and provide some context on how it's typically used or detected? I'm particularly interested in understanding the duration for which it remains detectable in the body and if there are any factors that might influence this lifespan. Additionally, I'm curious about the significance of EtG in relation to alcohol consumption and its potential use in forensic or medical testing.
