How is ulcerative colitis diagnosed?

A variety of diagnostic procedures and laboratory tests are used to distinguish ulcerative colitis from other conditions. First, your doctor will review your medical history and perform a complete physical examination. One or more of the following tests may be ordered:

  • Endoscopy, such as colonoscopy or proctosigmoidoscopy
  • Blood tests
  • Stool samples
  • Barium X-ray
  • Other X-ray procedures, such as magnetic resonance imaging (MRI), or computed tomography (CT scan)
