Tests and diagnosis

By Mayo Clinic Staff

If you have signs and symptoms that suggest you have prolactinoma, your doctor may recommend:

  • Blood tests. Blood tests can detect the overproduction of prolactin as a result of a pituitary tumor. Blood tests can also detect if levels of other hormones controlled by the pituitary are within the normal range. Women of childbearing age also will have a pregnancy test.
  • Brain imaging. Your doctor may be able to detect a pituitary tumor on an image generated by a magnetic resonance imaging (MRI) scan of your brain.
  • Tests of your vision. Such tests can determine if growth of a pituitary tumor has impaired your sight or peripheral vision.

In addition, your doctor may refer you for more extensive testing with a doctor who specializes in treating disorders of the endocrine system (endocrinologist).
