Chloride
Chloride is the main extracellular anion and works with sodium and bicarbonate to maintain fluid balance, blood pressure, and acid-base status. Abnormal levels often accompany kidney disease, dehydration, vomiting, or metabolic acidosis and alkalosis. Chloride is interpreted alongside sodium, bicarbonate, and the anion gap to characterize acid-base and volume disorders.
