These tests can help a doctor locate, diagnose, and sometimes treat a problem. Some tests require the digestive system to be cleared of stool, some require fasting, and others require no preparation.

Although diagnostic tests can be very useful in diagnosing the presence or absence of certain medical disorders, they can also be quite expensive and, in rare cases, cause bleeding or injury. It is important to discuss risks and benefits of a test with the doctor.
