What warmth should I store urine at?

I need to store urine for around 12 hours with as little detioration as possible. What is the best warmth to store it at? I know that it is normally 91-97 degree in warmth but is it better to store it cool, cold, frozen, room temperature, or what? Any REAL aid is appreciated, rants aren't please. Thank you for your time!What warmth should I store urine at?
of late stick it in your fridge door, it will keep hold of it cool but not really cold.
Trying to beat a drug experiment? Good luck. But how you going to conceal it? We're smarter than that.
If it is for a 12 or 24 hour urine sample, it is best to hang on to it refrigerated.
Keep it surrounded by a cool dry place at room temperature.
It will be fine surrounded by the refrigerator.
refrigerate it. but if you can, give the lab/doctor a fresh specimen.
