Psychogenic polydipsia will be diagnosed if polyuria is decreased after water deprivation test. CDI and NDI are distinguished by the vasopressin test ( Vasopressin administration will reduce the symptoms in CDI and not NDI).

decreased polyuria after water deprivation is a very subjective test you can measure urinary osmolraity after water deprivation, i.e dehydration test and it compares Uosm after dehydration Vs Uosm after vasopressin.
and CDI AND NDI as mention by Moozy
