Fecal Occult Blood Testing
Fecal occult blood is not visible to the natural eye and is typically the result of infrequent bleeding from within the upper or lower gastrointestinal tract. Since the bleeding is slow, it can go undetected as it does not change the color of the stool. Fecal occult blood is medically detected by fecal occult blood testing (FOBT), which is completed by capturing samples of stool. Occult bleeding is associated with other forms of rapid GI bleeding such as melena and rectal bleeding.
The Importance of Fecal Occult Blood Testing
At TransSouth Health Care, we may recommend fecal occult blood tests to detect colon cancer in individuals who have not yet experienced intestinal symptoms. Long before the aggressive development and symptomatic detection of potential colon cancer, a fecal occult blood test can detect colon cancer early. Early signs of colon cancer, especially colon polyps, can bleed slowly and create fecal occult blood. By detecting the cancers early and hopefully before they spread to other organs, patients can very well cut off the source of their cancer with surgical removal.
