WebElevated serum osmolality with normal sodium suggests possible hyperglycemia, uremia, or alcoholism. 1 Low serum osmolality may be secondary to overhydration, hyponatremia, syndrome of inappropriate antidiuretic hormone secretion (SIADH) with carcinoma of lung and other entities. Footnotes 1. Weisberg HF. WebSerum potassium levels are usually normal, but sodium may be low or high depending on volume deficits. Hyperglycemia may cause dilutional hyponatremia, so measured serum sodium is corrected by adding 1.6 mEq/L (1.6 mmol/L) for each 100 mg/dL (5.6 mmol/L) elevation of serum glucose over 100 mg/dL (5.6 mmol/L).
