I confirm with a 12 hour fast (no water!) and collect an 8 AM serum and urine osmolality. DI-High serum osmolality (>300 mOsm/kg), low urine osmolality (<500 mOsm/kg) and low AVP < 1pg/mL). Formal water deprivation test probably not needed.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
