Tests and diagnosis

By Mayo Clinic Staff

Tests your doctor may conduct to diagnose a pituitary tumor include:

  • Blood and urine tests. Tests of your blood and urine samples can determine whether you have an overproduction or deficiency of hormones.
  • Brain imaging. A computerized tomography (CT) or magnetic resonance imaging (MRI) scan of your brain can help your doctor judge the location and size of a pituitary tumor.
  • Vision testing. Such tests can determine if growth of a pituitary tumor has impaired your sight or peripheral vision.

In addition, your doctor may refer you to an endocrinologist for more extensive testing.
