How does EtG leave the body?

How exactly does EtG, a metabolite of alcohol, exit the human body? Is it primarily through urine excretion, or are there other significant pathways of elimination, such as sweating or breathing? Does the rate of EtG elimination vary depending on factors like age, weight, or hydration status? Understanding the detailed mechanisms of EtG excretion is crucial for accurate alcohol testing and interpretation of results.
