Crohn's Disease Diagnosis

Stool Sample
A stool sample is used to look for signs of intestinal bleeding or infection.
 
Upper GI Series With Small Bowel Follow-Through
An upper GI series is used to look for inflammation, sores, or other problems in the esophagus, stomach, and small intestine. For this test, the person drinks barium, a chalky solution that coats the lining of the small intestine, before x-rays are taken. The barium shows up white on x-ray film, revealing inflammation or other abnormalities in the intestine.
 
Barium Enema
A barium enema is a procedure that allows the doctor to assess the lining of the rectum and colon using x-rays. The patient is given an enema containing a barium solution, and air is pumped into the rectum. The barium and air outline the colon and rectum on the x-rays; however, the results of this test are often normal in people with early Crohn's disease.
 
CT Scan
A healthcare provider may recommend a CT scan to look for inflammation inside and outside the bowel. The patient drinks liquid containing barium and sometimes has a dye injected into his or her blood. Barium and this special x-ray dye show up on CT scans. Then the doctor uses a special machine to take many x-rays at different angles from around the body. The doctor studies the images with a computer. CT scans can spot inflammation, narrowing of the intestines, abscesses, and blockages.
 
Flexible Sigmoidoscopy
A flexible sigmoidoscopy is a procedure in which a soft, bendable tube with a camera on it is inserted through your anus to check for sores and inflammation in the rectum, and part of your large intestine.
 
Colonoscopy
A colonoscopy is a procedure similar to sigmoidoscopy, except that the whole colon is examined instead of just part of it. A colonoscopy is a valuable diagnostic tool, because your healthcare provider can look for certain types of inflammation that are characteristic of Crohn's disease. During the sigmoidoscopy or colonoscopy, if an abnormal area is seen, a biopsy may be taken. A biopsy involves taking a small piece of tissue from the lining of the intestines. This sample of tissue is then examined under a microscope to look for changes not visible to the naked eye.
