DETERMINING PRESENCE OF OCCULT BLOOD IN STOOL
a. General. The presence of blood in body waste is abnormal. Blood in the
stool may be bright red, which indicates that the blood is fresh and that the site of
bleeding is in the lower gastrointestinal tract. On the other hand, black-tarry-feces
means the presence of old blood and that the site of bleeding is higher in the
gastrointestinal tract. When blood is present in the stool but cannot be seen without the
use of a microscope, it is referred to as occult or hidden. A hemoccult test detects
occult blood in feces.
