About Chloride

What is chloride?

Chloride is an electrolyte important for regulating the body’s fluid balance and pH. Low chloride levels may occur as a result of vomiting and diarrhoea leading to dehydration. High levels may be caused by certain medications such as ibuprofen or may indicate the kidneys aren’t working normally.

Why take the test?

This test measures chloride levels in the blood and may be used to help investigate high blood pressure, kidney disease or heart disease.
