Fecal Immunochemical Test (FIT)

CRL’s Fecal Immunochemical Test (FIT) is a simple, non-invasive screening stool test that uses antibodies to detect blood in the stool. The presence of blood may be a sign of lower gastrointestinal bleeding that may be associated with conditions such as hemorrhoids, diverticulitis, ulcerative colitis, polyps, colorectal cancer, or other gastrointestinal lesions that can bleed. The Centers for Disease Control (CDC) recommends screening for colorectal cancer beginning at age 45.
