The doctor will ask about your symptoms and medical history. A physical exam will be done. The doctor will attempt to rule out other conditions, such as infection, that may be causing your symptoms.
The following tests may be done:
—A sample of your blood is taken and sent to the lab to be checked for anemia and signs of inflammation.
—You will provide a stool (feces) sample that will be examined for the presence of blood or infection.
—You will drink a liquid that contains barium; a series of x-rays will be taken that visualize the structure of the upper part of your digestive tract. The barium shows up on the x-rays and outlines your esophagus, stomach, and small intestine. This test may be done to check for Crohn’s disease.
—A fluid containing barium is injected into the rectum, and a series of x-rays are taken of your intestines. Barium makes your colon show up on x-ray. This test may be done to diagnose and evaluate the extent of inflammatory bowel disease.
—A thin, lighted tube is inserted into the rectum to examine the rectum and the lower part of the colon. The doctor will check for any abnormalities in the rectum, such as sores, redness, and fragile tissue.
—A thin, lighted tube is inserted through the rectum and into the colon to examine the lining of the entire colon. The doctor will check for any abnormalities associated with IBD.

—A sample of tissue from the colon is removed for testing. The tissue may be removed during a flexible sigmoidoscopy or a colonoscopy. A pathologist will examine the sample under a microscope.
