I get randomly tested through and out patient therapy program, due to a recent dui. They take the urine sample and give me the result almost immediately. I had a couple beers 48 hours prior to being alerted when I'll be tested. It can't be a EtG test since it's not sent out to a lab, correct? So I have nothing to worry about, right? Thank you so much!

You very well might fail. Why do you think a labs not doing it? A lot of hospitals/larger medical practices have in house labs.
