Maybe if you dilute it enough by drinking a ton of water or throw some extra warm water in you'll pass if they are only doing a strip dip test. They might be suspicious of it being clear though and if your unsure or its being sent to a lab I would certainly substitute someone else's warm clean piss in there or even your dogs if a clean human is unavailable. Remember urine comes out of the body sterile anyway and shouldn't have bacteria in it until its sat for a while (or the person has an infection). So don't be afraid of carrying someone else's urine, its not gonna give you hiv if you spill some. Good luck on passing to keep the job.
