Urine osmolality, serum osmolality, and urinary sodium concentration are the essential laboratory tests used in the evaluation of patients with hyponatremia. Together with the history and the physical examination, they help to establish the primary underlying etiologic mechanism. In general, the etiology of the hyponatremia directs its management. TSH and serum cortisol levels may be obtained if hypothyroidism or hypoadrenalism is suspected.
