In general, if someone has an increased serum osmolality, it is due to either decreased water in the blood or increased solutes. If the person has decreased serum osmolality, it is due to increased fluid levels.
A comparison of the urine osmolality to the serum osmolality yields additional information about water handling by the kidney or abnormalities of urine concentration or dilution, as does electrolyte studies. Typically, the ratio of urine osmolality to serum osmolality is 1-3.n a healthy state, the specific gravity of the urine corresponds to the urine osmolality. An evaluation of the osmolality, either routinely or under artificial conditions, indicates the kidneyâs ability to maintain tonicity and water balance of the extracellular fluid.
