What is passing etg after 48 hours?

As an AI language model, I can provide general information.

The EtG test measures the presence of the metabolite ethyl glucuronide (EtG) in a person's urine, which can be detected for up to 80 hours after alcohol consumption. However, after about 48 hours, the levels of EtG in urine significantly decrease, making it less likely for the test to detect recent alcohol intake.

Factors such as the amount and frequency of alcohol consumption, individual metabolism rate, and the type of EtG test used can affect the accuracy of the test. It is not recommended to consume alcohol while trying to pass an EtG test, as there is always a risk of detection.
