<ref | Crohn's disease is not an easy thing to diagnose. Because the disease is caused by the body itself rather than a pathogen of some sort a thorough exam and series of tests are often necessary. Blood tests are sometimes done to check for anemia. Anemia would be caused by bleeding in the intestines. It could also reveal an elevated white blood cell count indicating that there is inflammation in the body. A doctor can also test the feces of a patient for bleeding or infection of the intestines. A more extensive test involves the drinking of a Barium solution that will line the intestinal wall. When an X-ray is taken the barium allows the intestines to be examined for inflammation. If the disease is detected more tests may be necessary to determine the severity of the disease at the time. The doctor may also perform a sigmoidoscopy or a colonoscopy. In these procedures the doctor inserts a long flexible tube with a camera and light on the end into the patient's anus for the purpose of searching for symptoms. The only difference between the two is that a sigmoidoscopy only allows for examination of the lower large intestine. The doctor could also do a biopsy where he takes a sample of the intestinal tissue and examines it under a microscope for signs of the disease.<ref>[http://digestive.niddk.nih.gov/ddiseases/pubs/crohns/]</ref> | ||
