Our current diagnostic test concepts of DI date back to animal studies from Gilman and Goodman 7576 in the s, which first demonstrated that osmotic stimulation by dehydration 7576 or hypertonic saline infusion 77 induces an antidiuretic urinary response that is not observed in hypophysectomized dogs Celebrating a century of vasopressin therapy. After 2 to 3 hours of cessation of fluid intake, the urine volume and osmolality should reprivation measured every hour and the insipiduz sodium and plasma osmolality every 2 hours.

Under these circumstances, intact thirst sensation is essential to restore normal osmolality, but often at the expense of a clinically pronounced polyuria and polydipsia.
