bicarbonate (HCO3-)

[bīkär′bənāt]
Etymology: L, bis, twice, carbo, coal
an anion of carbonic acid in which only one of the hydrogen atoms has been removed, as in sodium bicarbonate (NaHCO3). Also called hydrogen carbonate.

bicarbonate

A salt containing the anion HCO3-, which is the most important buffer in the blood, it is regulated by the kidney, which excretes it in excess and retains it when needed; it increases with ingestion of excess anti-acids, diuretics and steroids; it is decreased with diarrhoea, liver disease, renal disease and chemical poisoning.

Specimen
Bicarbonate is usually measured in serum as total CO2.
 
Ref range
24–26 Meq/L.

bicarbonate

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.
