Sodium and potassium are the cations present in highest concentrations in the urine. The urinary sodium result is included, with chloride and potassium, in the urinary electrolyte panel. Urinary electrolytes and osmolality are used in the evaluation offluid, electrolyte, and/or acid-base disorders. Urine sodium can be ordered as an individual test and can be measured using either random or timed urine collections.
