the place i get random drug tests, test for nitrite. if i have synthetic urine & have exposed it to air. if i don't use the day i open the bottle will it grow bacteria & test positive for nitrite? or is that just a very specific bacteria & would have nothing to do with it being exposed to air?

if anyone knows, let me know
