Tests and diagnosis
By Mayo Clinic staffTests 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 for more extensive testing to a doctor who specializes in treating disorders of the endocrine system (endocrinologist).
