Crohn's Disease Health Center

If a doctor notices any of the following during a physical exam, he or she may suspect Crohn's disease.

  • abdominal mass
  • abdominal tenderness
  • mouth ulcers
  • joint Swelling

The following tests can be used to diagnose Crohn's disease:

  • barium enema or upper GI series
  • colonoscopy or sigmoidoscopy
  • computed tomography (CT scan) of the abdominal area
  • endoscopy or capsule endoscopy
  • magnetic Resonance imaging (MRI) of the abdominal area
  • enteroscopy

A doctor might also request a stool culture to make sure the symptoms are not caused by something else.

Crohn's disease can also change the results of these tests:

  • albumin
  • c-reactive protein
  • erythrocyte sedimentation rate
  • fecal fat
  • hemoglobin
  • liver function tests
  • white blood cell count
