PITUITARY INVESTIGATIONS

1. Prolactin - prolactinoma.
2. 24hr urinary free cortisol - for ACTH excess.
3. 1mg Dexamethasone overnight suppression test - for ACTH, cortisol excess.
4. ACTH stimulation test - cortisol deficiency.
5. FSH + LH - gonadotroph.
6. Alpha-subunit - inactive pieces of glycoprotein that indicate that a pituitary mass is definitely pituitary and not a craniopharyngioma.
