Diverticulitis - Exams and Tests
SYMPTOMS & TREATMENTS
Your doctor will take a history and do a physical exam if diverticulitis is suspected. Depending on your symptoms, you may have one or more tests to rule out other medical problems that could be causing your symptoms. The extent of testing will depend on how bad your symptoms are and how long they have lasted.
Routine tests
These tests may be done any time you see your doctor about abdominal pain or other symptoms.
- Complete blood count (CBC) may show if you have an infection or if you have too few red blood cells in your blood, possibly because of bleeding in the colon.
- Urinalysis may show you have a urinary tract infection.
- Abdominal X-ray may provide clues about the cause of abdominal pain and other symptoms.
- The digital rectal exam looks for tenderness or a mass in the lower pelvic area.
- The fecal occult blood test looks for blood in your stool.
Tests done as needed
Depending on your symptoms, your doctor may want to do one or more of these tests.
- A computed tomography (CT) scan may be done if symptoms suggest you have a pocket of infection (abscess) in your abdomen or that a pouch (diverticulum) has burst. The scan also can reveal other possible causes of your symptoms.
- A
barium enema X-ray may be used to show
diverticula or other possible causes of your symptoms.
But a barium enema X-ray usually is not done while you are having an attack of
diverticulitis because of the risk that the barium might spill into the
peritoneum (the lining of the abdominal cavity) if you
have a perforation. A material that performs a function similar to barium but
that can dissolve in water (water-soluble contrast) may be used instead. See

normal colon
and of
diverticulosis . - Flexible sigmoidoscopy and colonoscopy may be used if your main symptom is bleeding from the intestine. These tests also may be done to look for narrow spots or growths in the intestine and to rule out ulcerative colitis or cancer. But sigmoidoscopy and colonoscopy are not usually done while you are having an attack of diverticulitis because of the risk that the scope could tear the lining of the colon (perforation). If this happens, the infection could spill into the peritoneum (the lining of the abdominal cavity), causing a more serious infection.
If you are having serious bleeding from the intestine, a condition called diverticular bleeding, your doctor may want to do:
- A technetium-labeled red blood cell bleeding scan, to find the source of bleeding.
- Angiogram (also called arteriogram), to locate the source of bleeding if you are having a large amount of bleeding in your intestine.
See the topic Diverticular Bleeding for more information.
