What kind of procedures might follow a positive FOB test?
Before or after you have an FOB test, you may have a rectal examination. A positive FOB test may be followed by: • Sigmoidoscopy: an examination of the rectum and lower colon (part of the intestines) with a lighted instrument to look for abnormalities, such as polyps; • Colonoscopy: a more thorough examination of the rectum and entire colon; and • A double contrast barium enema: a series of X-rays of the colon and rectum.
