WebUrine osmolality. Urine osmolality is a measure of urine concentration, [1] in which large values indicate concentrated urine and small values indicate diluted urine. Consumption of water (including water contained in food) affects the osmolality of urine. [2] Osmolality is measured by osmometer, which evaluates the freezing point depression of ... WebThe "Osmolal gap" represents osmoles which are unaccounted for by sodium salts, glucose and urea. Osmolal gap = Measured Osmolality - Calculated Osmolality. In normal individuals, the osmolal gap is <10 mOsm/kg water. In the event a significant osmolal gap is detected, the following causes should be considered: Ethylene glycol ingestion
