Diagnosis and evaluation may involve assay of pituitary or target gland hormones.
Dynamic stimulation tests may assist to evaluate hormone reserves: insulin hypoglycaemia stimulation test is usually sufficient; rarely, stimulation tests using gonadotrophin releasing hormones are occasionally of value - consult pathologist.
Patients may have clinical or radiological evidence of a space occupying lesion in the pituitary fossa.
They may present initially with deficiency of a single hormone: prolactin, testosterone (in males), LH, FSH (in post-menopausal females), TSH, thyroxine (free), cortisol.

Empty sella syndrome
Single hormone deficiency
May be the presenting feature of any cause of panhypopituitarism, however single hormone deficiency can occur and is usually genetic.
Growth hormone stimulation test.See Short stature
Growth hormone resistance, rather than deficiency; growth hormone levels are usually high.
