Tests to Diagnose Pituitary Disorders
A pituitary disorder can be difficult to diagnose. The OHSU Northwest Pituitary Center offers all types of tests to diagnose pituitary disorders.
You might have tests for the following hormones:
- 8:00 a.m. serum cortisol and adrenocorticotropic hormone (ACTH) (or cortrosyn stimulation test)
- Thyroid stimulating hormone (TSH) and free T4
- Luteinizing hormone (LH) and Follicle stimulating hormone (FSH)
- Testosterone (men), estradiol ( women)
- IGF-1 (insulin-like growth factor-1)
- Salivary cortisol, 24-hour urine free cortisol (if you think you may have Cushing's disease)
You may also have magnetic resonance imaging of your head with and without gadolinium (contrast dye).
If you have a pituitary tumor or other disorder, your doctor will probably have you see a doctor who specializes in pituitary disorders. Treatment usually includes a combination of medicine and surgery. You might also have radiation therapy. If you have surgery, you should see a doctor who specializes in pituitary disorders before and after the surgery.
