Chloride, Urine, 24 Hour
Test Code
UCL24
Description
Urine chloride excretion approximates the dietary intake. The chloride content of most foods parallels that of sodium. An increase in urine chloride may result from water deficient dehydration, diabetic acidosis, Addison's Disease, and salt-losing renal disease. Decreased urine levels are seen in congestive heart failure, severe diaphoresis and in hypochloremic metabolic alkalosis due to prolonged vomiting.
