Fecal occult blood (FOB) refers to blood in the feces that is not visibly apparent. A fecal occult blood test (FOBT) checks for hidden (occult) blood in the stool (feces). Newer tests look for globin, DNA, or other blood factors including transferrin, while conventional stool guaiac tests look for heme.

Famous quotes containing the words occult and/or blood:
“The greatest delight which the fields and woods minister, is the suggestion of an occult relation between man and the vegetable. I am not alone and unacknowledged. They nod to me, and I to them.”
—Ralph Waldo Emerson (1803–1882)
“Communism, my friend, is more than Marxism, just as Catholicism ... is more than the Roman Curia. There is a mystique as well as a politique.... Catholics and Communists have committed great crimes, but at least they have not stood aside, like an established society, and been indifferent. I would rather have blood on my hands than water like Pilate.”
—Graham Greene (1904–1991)
