\text{ADH} = 100 - 50 = 50

Hydration50%

ADH level50%

Urine volume65 mL/hr

Urine concentration700 mOsm/kg

Hydration level50

Set hydration to 0 (fully dehydrated) — confirm ADH reads 100%
Set hydration to 100 (fully overhydrated) — confirm ADH reads 0%
On full dehydration, confirm urine volume is at its minimum (30 mL/hr) and concentration at its maximum (1200 mOsm/kg)
On full overhydration, confirm urine volume is at its maximum (100 mL/hr) and concentration at its minimum (200 mOsm/kg)
Set hydration to exactly 50 (balanced) — confirm ADH sits exactly at the midpoint, 50%
