Test eludes me. If I drank 3 sips of alcohol (2 sips of beer, 1 sip of scotch) Saturday night, this would not show up in an ETG (500 ng)test taken Monday afternoon? I would assume it wouldn't but if there is no alcohol in my system it wouldn't store it and then somehow show up? I understand the test is very sensitive and I am not trying to beat it, I just would like to learn about it. Thank you very much.

I passed my test.
