Chloride, 24-Hour Urine

This test measures the total amount of chloride passed in your urine over a full 24-hour period. Chloride is an essential mineral that helps your body maintain proper fluid levels and acid-base balance. Doctors use this test to investigate the cause of persistent acid-base imbalances, helping to distinguish between issues caused by fluid loss and those caused by hormonal disorders. While it helps identify the source of the imbalance, this test cannot diagnose a specific condition on its own and is usually evaluated alongside blood electrolyte levels.
