how long does refrigerated urine stay good
IamN2pot said: Always keep human urine in an air tight container. It will remain good at room/body temp for at least 8 hours, refrigerated up to 30 days and frozen up to 1 year.Hope that helps.ll at room temp (except for the plane ride in the cargo hold). None have ever come back to me as no good or expired. I actually have no idea how long urine can be kept at room temp, refrigerated, or frozen. I do know that I keep urine longer than 8 hours until the delivery service gets here.
