According to Cornell University, a urine specimen can be held for up to twelve hours, providing that it has been refrigerated. In addition to time restraints, temperature of the urine can also play a critical role in the end test result. Refrigerated specimens must be allowed to become room temperature before testing.
When I know I'll be tested, I thaw the urine at room temperature overnight (still sealed). At most it's at room temp for 6-8 hours. There will invariably be sediment collected at the bottom of the sample and that is normal. frozen urine sample can last up to one year. I haven't tested this-but it seems to be the general consensus on these forums and on other discussions I've seen on the net. I've used urine stored for over a month without complications, so using yours after a week of storage should be fine.
