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. WebSerum osmolality greater than 295 mmol/kg (high osmolality) indicates hypertonic hyponatraemia. Consider hyperglycaemia as a spurious cause of hyponatraemia, due to movement of water from the intracellular to extra-cellular space. See the CKS topic on Diabetes - type 2 for information on how to investigate for underlying type 2 diabetes.
