WebPlasma osmolality measures the body's electrolyte–water balance. There are several methods for arriving at this quantity through measurement or calculation. Osmolality and osmolarity are measures that are technically different, but functionally the same for normal use. Whereas osmolality (with an "l") is defined as the number of osmoles (Osm) of … WebNote: this study examined urea instead of blood nitrogen urea (BUN), so urea was divided by 6, instead of the 2.8 factor that is used with BUN.
