CO
2 content (also known as "Total CO
2") is a blood test that usually appears on a "Chem 19" or an electrolyte panel. The value measures the total dissolved Carbon dioxide (CO
2) in blood. It is determined by combining the Bicarbonate (HCO−
3) and the partial pressureofCO
2 multiplied by a factor which estimates the amount of pure CO
2 that is dissolved in its natural form (usually 0.03).[citation needed]
One given reference range is 24–32 mEq/L.[1]
