…be apparent from the clinical context There are two mechanisms, other than sporadic laboratory errors, which cause the measured serum osmolality to be significantly higher than the calculated value: …
…the effective circulating volume and plasma osmolality within relatively narrow limits, as well as to maintain electrolyte homeostasis. The normal homeostatic mechanisms that maintain the effective circulating …
…understood; however, one mechanism may be that the rise in serum osmolality induced by the rise in serum sodium during dialysis may be counterbalanced by a fall in serum osmolality induced by the removal …
