Term Description

Concentration of bicarbonate in plasma separated anaerobically from whole blood at 38 degree Celsius and equilibrated at a pCO2 of 40 mm Hg with the blood Hb fully saturated with oxygen. It is a measure of the acid-base balance in a sample of blood after the correction of a respiratory disorder. As a result, abnormal values for standard bicarbonate reflect only the metabolic component of an acid-base disturbance. Elevation indicates metabolic alkalosis, while depression indicates metabolic acidosis.

Part Description

LP15441-6   Bicarbonate
Bicarbonate is an electrolyte and typically measured along with other electrolytes (e.g. sodium, potassium, and chloride) to detect, evaluate, and monitor electrolyte imbalances. Low bicarbonate levels may occur in patients with Addison's disease, chronic diarrhea, diabetic ketoacidosis, and kidney disease. Increased levels may be seen in patients with severe vomiting, cushing syndrome, and metabolic alkalosis. Various drugs may also increase or decrease biocarbonate levels.[Lab Tests Online: co2]
Bicarbonate and total CO2 are not synonyms. Total CO2 = bicarbonate + CO2 + carbonic acid. Under normal circumstances, bicarbonate is the primary constituent of total CO2, however, in certain pathologic conditions, CO2 and/or carbonic acid contribute a clinically significant fraction of the total.
