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:
“Capital is money, capital is commodities.... By virtue of it being value, it has acquired the occult ability to add value to itself. It brings forth living offspring, or, at the least, lays golden eggs.”
—Karl Marx (1818–1883)
“What if I look upon a man
As though on my beloved,
And my blood be cold the while
And my heart unmoved?
Why should he think me cruel
Or that he is betrayed?”
