HCO₃ Nephrology A general term for any salt containing the anion HCO₃–, which is the most important buffer in the blood; bicarbonate is regulated by the kidney, which excretes it in excess and retains it when needed; it is ↑ in ingestion of excess antiacids, diuretics, steroids; it is ↓ in diarrhea, liver disease, renal disease, chemical poisoning.
