WebJan 24, 2024 · Serum osmolality is affected by the concentration of blood chemicals like chloride, sodium (Na), proteins, bicarbonate, and glucose. The blood urea nitrogen (BUN) measurement is important for calculating serum osmolality. Specific therapies and toxins that affect an individual’s fluid balance should also be evaluated with serum osmolality. WebJan 25, 2024 · The formula called Worthley equation (Osm = 2* [Na + ] + BUN (mg/dl)/2.8 + Glc (mg/dl)/18) was accepted as the most accurate calculation equation and calculations were made with this formula in our study [ 4, 22, 23 ]. The osmometer used in our laboratory is measuring the osmolality by vapor pressure method.
