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.
So Lets break this down and figure out how many hours pee is good forâ¦. Urine can stay fresh at room temps for about 5 hours You can keep frozen pee for a very long time, thatâs if stored properly Pee stays good in glass for long term, 5 plus hours.
