Irritable Bowel Syndrome Evaluation
Testing is usually required to make the diagnosis of irritable bowel disease. Tests help to detect other conditions that cause symptoms similar to irritable bowel disease.
Tests that may be used to evaluate irritable bowel disease include:
- Complete blood count
- Liver profile
- Kidney profile
- Intestinal tissue biopsy
- Allows a doctor to look inside, take tissue specimens, and remove any questionable growths or polyps.
Imaging studies that may be used to evaluate irritable bowel disease include:
- Barium enema
- CT scanning of the abdomen
- MRI scan of the abdomen
- Virtual colonoscopy:
- Uses a special type of CT scanner that takes many pictures of the colon in super thin slices. A computer reassembles the images into a 3-D model of the colon. The more slices the CT scanner is capable of taking in rapid succession, the better the image quality.
