Ok...so I am supposed to go for me UA tomorrow...and I am feeling pretty good about the whole subbing thing but my one issue at this point is I can't get over how QF smells like basically..nothing. I've read on here that it's not unusual for urine to not have an odor but I mean, if someone smells it and it's odorless..is that an immediate red flag? Can they fail based on lack of odor?
