How long can urine be stored before testing?
In most cases urine should be tested immediately. Urine testing becomes less effective as the urine cools. The optimal urine test is at body temperature.
If properly sealed and stored, urine samples are good for testing up to 24 hours after the sample given. The urine sample should be in a sterile container within a sealed plastic bag and stored in a refrigerator.

The reason it is important that the urine be kept in an air-free and dark environment, is because of mold. A cool storage area will help prevent mold from growing.
