Drug test

So like most of the users on here i have a dilemma on my drug test. Mine is a little different in my experience and i hoPe someone has done this. My drug test and Physical are being done at a hospital so i have never been tested threw a hospital, is it the same as Places like concentra or labcorp? I was told they test you by pissing in a toilet and if it turns a different color that determines if your dirty, ima try and talk to a co-worker tommarow for more info. I wanted to use quickfix but as you kno hospitals can take hours to see someone, any thought? Hopefully i can get better info tommarow and post up.

Also i was wondering if the 2oz bottle of QF is enough or if i should get more?

is it for a job? my drug test was also at a hospital.

Ya, its for a job with the county im in. I am just worried cause the one guy who went already was there for like 5 hours
