Occult means you do not know there is blood in the stool, i.e., you cannot see bright red recognizable blood like you might see if you had bleeding from hemorrhoids. Testing for fecal occult blood is commonly used as a cancer screen for colon cancer. A positive test can mean other conditions however. A review article, Rockey DC: Occult gastrointestinal bleeding. N Engl J Med 1999;341:38-46 addresses some questions you might have if you turned out to have a positive test.
