The serum or plasma osmolality is a measure of the different solutes in plasma. Among other applications, serum osmolality is indicated to evaluate the etiology of hyponatremia and may be used to screen for alcohol intoxication by means of the osmolal gap.
Water movement between body fluid compartments is regulated by the effective osmolality of the solutes within each compartment. Sodium is the main determinant of plasma osmolality, and water moves toward body compartments with higher osmolality and away from those with lower osmolality.
