Fecal Occult Blood Examination using the latest immunological-based test.
This test should be performed every year to check for tiny amounts of blood in the stool. FOBT involves placing a small amount of stool on a test pack. New FOBT uses the latest immunological-based test which does not require fasting and diet preparations. In concert with an FOBT, a flexible sigmoidoscopy should be done every 3 years. A positive FOBT should warrant a complete colonoscopy.
