WebA normal or elevated effective serum osmolality (280 mOsm/kg or greater) suggests pseudohyponatremia. Hypertonic states, like hyperglycemia or mannitol use, can cause hyponatremia by drawing water extracellularly and lowering serum sodium concentration. This is technically a true (not pseudo) hyponatremia.
