Many diseases are difficult to diagnose or present with no symptoms that would suggest that
medical diagnosis is needed until significant bodily damage has occurred. We disclose a medical
toilet that may be used to diagnose
disease. The
toilet comprises a conduit through which volatile organic compounds travel from the
toilet bowl to the environment outside the toilet. The invention includes methods that comprise the steps of training an animal to identify the scent of bodily waste collected from a user that is afflicted with a defined
disease. A user's bodily waste is deposited into the medical toilet and the animal is then exposed to the volatile organic compounds traveling through the conduit on the medical toilet. The animal performs an act that signals that the animal has perceived the smell associated with the
disease. Thus, we disclose a novel device for diagnosing disease and methods of user thereof.
