Chloride, 24 Hour details
What Chloride, 24 Hour shows
Chloride is an electrolyte that works closely with sodium to help control fluid balance, blood pressure and acid-base balance. Most chloride comes from salt in your diet, and the kidneys regulate how much is kept or passed in urine. This test measures the total chloride in all the urine you collect over 24 hours. It helps look at salt intake, kidney handling of electrolytes, and causes of abnormal blood chloride or acid-base problems. A higher result often reflects higher salt intake or certain medications such as diuretics, while a lower result can occur with low salt intake, vomiting or fluid loss. Results depend on a complete collection and are read with blood electrolytes and creatinine.
Tests that include Chloride, 24 Hour
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.
- Chloride, 24 Hour Measures the total chloride passed in your urine over 24 hours, helping assess salt and fluid balance and causes of abnormal blood electrolytes.
- Chloride/Creatinine Ratio A calculated ratio of chloride to creatinine in your 24-hour urine, used to put urinary chloride in context of urine concentration and collection.
- Creatinine, 24 Hour Measures the total creatinine passed in a 24-hour urine collection, used to check the collection is complete and to calculate kidney function and other urine results.
