Normal urine sodium and osmolality
WebThe urine sodium and creatinine and serum and urine sodium are key to diagnosing the cause of hyponatremia. 1. First, measure serum osmolality (low < 265 mOsm/kg water, normal 265–280 mOsm/kg water, high > 280 mOsm/kg water). Most patients with hyponatremia will have low osmolality; normal serum osmolality suggests … WebThe ratio of urine osmolality (Uosm) to plasma osmolality (Posm) is useful to determine the ability of the kidneys to concentrate or dilute urine.. A Uosm:Posm ratio greater than 1 indicates that the kidneys are able to concentrate urine. • A Uosm:Posm ratio of 1 indicates that water and solute are being excreted in a state that is iso-osmotic with plasma.
