Fecal Occult Blood

Fecal occult blood is present in colon cancer, colon polyps, and rectal polyps. In addition, hemorrhoids, intestinal injuries, and anal fissures can also result in fecal occult blood. However, the amount of occult blood present in stool is so minimal that laboratory tests are needed to confirm its presence. The fecal occult blood test detects the presence of occult blood.
