What does the Chloride (Cl) test measure?

The Chloride (Cl) test specifically measures the level of chloride in the blood. Chloride is an electrolyte that plays a vital role in maintaining fluid balance, osmotic pressure, and acid-base balance in the body. It works closely with other electrolytes such as sodium and potassium.

Monitoring chloride levels is essential in evaluating a patient's electrolyte balance and kidney function, as well as diagnosing conditions like dehydration, kidney disease, and metabolic disorders. Thus, the Chloride test is focused solely on determining levels of chloride in the bloodstream, making it a key indicator of various physiological functions.
