How to interpret serum and urine osmolality

WebA common simplified formula for serum osmolality is: Calculated osmolality = 2 x serum sodium + serum glucose + serum urea (all in mmol/L). 1 Osmolality can also be … WebThe osmolality is monitored through osmoreceptors in the hypothalamus which can detect a 1% change in osmolality. ADH is secreted from the posterior pituitary and acts on the collecting duct increasing resorption of water. The level of ADH is maximal at levels of osmolality above 295 mOsmol/kg, and undetectable at less than 280 mOsmol/kg.

In SIADH, hyponatraemia is due to inappropriate secretion of antidiuretic hormone (ADH). In a normal physiological state, ADH is released in response to increased serum osmolality, whereas in SIADH, ADH secretion is unregulated.
