Answer

Additional studies that may be indicated include the following:

  • Water deprivation (Miller-Moses) test to ensure adequate dehydration and maximal stimulation of ADH for diagnosis

  • Pituitary studies, including magnetic resonance imaging (MRI) and measurement of circulating pituitary hormones other than ADH

See Workup for more detail.
