Tests and diagnosis
By Mayo Clinic staffBlood 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. Additionally, your doctor may recommend:
- Brain imaging. Your doctor may be able to detect a pituitary tumor on an image generated by a computerized tomography (CT) or 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).
