Chloride, 24‑Hour Urine without Creatinine
Use
Urine chloride excretion approximates dietary chloride and parallels that of sodium intake. Increased urinary chloride levels can result from water‑deficient dehydration, diabetic acidosis, Addison’s disease, and salt‑losing renal disease. Conversely, decreased urinary chloride levels are associated with congestive heart failure, severe diaphoresis, and hypochloremic metabolic alkalosis due to prolonged vomiting.
