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.
Please submit a 10 mL aliquot of a 24-hour collection. Collect urine

include first morning specimens; collect all subsequent voiding. The
last sample collected should be the first morning specimen voided
the following morning and the same time as the previous morning's
first voiding. Record 24-hour urine volume on test request form and
urine vial. Transport at room temperature.
