Chloride (Cl): Results
Content provided by Healthwise
Results
A chloride test measures the level of chloride in your blood or urine. Chloride is one of the most important electrolytes in the blood, along with sodium, potassium, and calcium. Chloride helps keep the amount of fluid inside and outside of your cells in balance.
Normal
Normal results may vary widely from lab to lab. Blood chloride levels are checked more often than urine chloride levels. Results are usually available in 1 to 2 days.
