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.
