Chloride

Clinical Chemistry

Description

Chloride is a major anion in the extracellular space and is important in maintaining the normal acid-base balance, as well as the normal levels of water in the body. It is supplied primarily through the diet, absorbed in the gastro-intestinal tract, and excreted via the kidneys. 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. Chloride measurements are of value in the calculation of the anion gap (Na + K) - (Cl + Bic), which aids in determining the cause of an acidosis.
