Urine specimens should not remain unrefrigerated for longer than two hours. Aurine specimen that cannot be delivered to a laboratory within two hours should be stored in a refrigerator. The reason for this precaution is that urinesamples undergo chemical changes at room temperature.
The human body decomposes rapidly after death. Care must be taken to keep the body as cool as possible in order to slow the decomposition that results in noxious odors and the leakage of body fluids from body orifices. A human body can be kept in a cool room for at least 24 hours before decomposition begins. Heat in the room should be turned off in the winter, and air conditioning should be turned on in the summer. Ice can be used instead of refrigeration if necessary.
