[Functional diencephalo-pituitary diagnosis by means of radioimmunoassay]

The Author, after mentionating the always increasing need of cooperation between the clinical activity and the laboratory research, stops considering the semeiological meaning of the radioimmunoassay of the pituitary hormones. However he worns against the limitations that such dosages present at the base line and the possible dissociation between immunological activity and biological activity. He describes then the dynamic tests able to determine variations of hormonal levels and makes his conclusions stating that the observation made during dynamic conditions may be of help to the clinical diagnosis.
