According to Cornell University, a urine specimen can be held for up to twelve hours, providing that it has been refrigerated.

Storing a stool sample. Stool samples should be handed in as soon as possible, as some can't be analysed if they've been refrigerated â your doctor will tell you if this is the case. If you can't hand the stool sample in immediately, you should store it in a fridge, but for no longer than 24 hours. Place the container in a sealed plastic bag first. Stool samples must be fresh â if they aren't, the bacteria in them can multiply.
