I had one beer around 12pm yesterday and have to take an EtG test today. How long would be the maximum time for EtG to be detectable on a 500ng test..
How about a 100ng test.

What happens if you FAIL ?

I donno

Maybe you should find out - or does wherever you are just grab people off the street and test them.

Probation? Employment?

Apparently the OP donno.

I just want an answer to the question haha

Haha, the person doing the testing will let you know. Maybe that person can also explain why you are being tested.

I'd ask.
