For many centuries, it has been suspected that examination of stool could provide insights into the state of health or disease of an individual. The Egyptians were concerned with the shape and consistency of stool (Eber's papyrus, 207), and 19th century Americans were concerned with "poisons and gases" (1); more recently, the components of stool (e.g., pathogens, occult blood, fats, and bile acids) have been the subject of scrutiny.
Within the past two decades, with the advent of the polymerase chain reaction (PCR) technique, came the ability to amplify tiny numbers of specific DNA sequences. This advance has permitted the identification of not only mutations that accumulate in neoplasms and define their progression to
