Other tests may be done to confirm or evaluate the disease.
Biopsy: This test is done on a sample of tissue collected during sigmoidoscopy or colonoscopy. A biopsy also may be done to find out
if a tumor is present. Bowel biopsies are painless (other than the possible discomfort
of the scope procedure). They remove only a tiny piece of tissue.
Video capsule endoscopy (VCE): This test takes pictures of the digestive tract using a tiny camera that you swallow. The images are recorded by a device that you wear on your belt. The test allows your doctor to see the small intestine, which is hard to see with other
Small bowel enteroscopy: This test uses a long, lighted flexible
tube with a tiny camera that sends pictures of the small intestine to a video
screen. This helps the doctor look at the small intestine. The doctor can also
take small samples of the tissue.
Blood tests to find antibodies: These tests can sometimes help the doctor tell if you have Crohn's disease or ulcerative colitis. These tests include anti-neutrophil cytoplasmic antibody with perinuclear staining (pANCA), anti-Saccharomyces cerevisiae antibody (ASCA), and outer membrane porin C (Omp C).
