Chloride

What is the role of chloride in the body?

A chloride test measures the level of chloride in your blood or urine. Chloride is one of the most important electrolytes in the blood. It helps keep the amount of fluid inside and outside of your cells in balance. It also helps maintain proper blood volume, blood pressure, and pH of your body fluids.

Foods with higher amounts of chloride include seaweed, rye, tomatoes, lettuce, celery, and olives. Chloride, combined with potassium, is also found in many foods. It is most often the main ingredient in salt substitutes.
