real urine

hey guys, just got informed that the rules have changed for the random.
intially we had 48 hrs to get the test done, time was on my side,
that changed today to " when your notified" go to the lab and get tested.
I have the urinator and the QF 5.7 so i should relax, but were talking 70,000 a year.
I have clean donors everywhere, just not when I need'em.
If I were to put a clean sample [real] in a thermos [ keep in fridge at night,car during workday] would it be good for a week at a time ?
I should just chill and trust QF, I'm just paranoid :jointsmile:
