Urine osmolality is a measure of urine concentration, in which large values indicate concentrated urine and small values indicate diluted urine. In healthy individuals with restricted fluid intake, urine osmolality should be greater than 800mOsm/Kg, while a 24 hour urine osmolality should average between 500 and 800 mOsm/Kg and a random urine osmolality should average 300 and 900 mOsm/Kg.
