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 and whether 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 scan of your brain.
  • Vision tests. These can determine if a pituitary tumor has impaired your sight.

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