Rectal biopsy

  • Alternative Names

    Biopsy - rectum

    Normal Values

    The anus and rectum appear normal in size, color, and shape. There should be no evidence of bleeding, polyps, hemorrhoids, or other abnormalities. When biopsy tissue is examined under a microscope, no abnormalities should be noted.

    What abnormal results mean

    This test is a common way to confirm amyloidosis. It also determines the specific causes of abnormal conditions of the rectum, such as colitis. Other findings could include:

    • Abscesses
    • Colorectal polyps
    • Infection
    • Inflammation
    • Tumors

    The test may be also performed for:

    • Crohn's disease
    • Hirschsprung's disease in infants
    • Ulcerative colitis
