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.
Stool analysis: This may be done to look for blood, signs of bacterial infection, malabsorption, parasites, or
the presence of white blood cells. It can help tell the difference between Crohn's
irritable bowel syndrome (IBS), which can have similar symptoms.
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).
