Test Summary
The fecal occult blood test detects peroxidase activity from blood in fecal samples. This is a useful screening aid for detecting primarily lower gastrointestinal (G.I) disorders that may be related to diverticulitis, ulcerative colitis, polyps, adenomas, colorectal cancers or other G.I. lesions that can bleed. It is recommended for use by health professionals as part of routine physical examinations and in screening for colorectal cancer or other sources of lower G.I. bleeding.
