Clinical Utility

Chloride is the major extracellular anion and serves to regulate the balance of extracellular fluid distribution. Common causes of decreased chloride include reduced dietary intake, prolonged vomiting and reduced renal reabsorption as well as some forms of acidosis and alkalosis. Increased chloride values are found in dehydration, kidney failure, some forms of acidosis, high dietary or parenteral chloride intake and salicylate poisoning.
