Clinical Notes

Chloride is an electrolyte that is present in body fluids. Electrolytes are minerals that hold an electrical charge. Electrolyte levels are closely linked to the balance of fluids in the body and the pH of body fluids. pH is another way of describing the level of a fluid’s acidity or alkalinity, which is also called acid-base balance.
