What does low level of CO2 from a blood test mean? The blood is used to transport carbon dioxide out of the body. All the body organs and tissues require oxygen to perform their functions and to stay alive. The waste product of the process of metabolism is carbon dioxide. Some of the carbon dioxide is dissolved in the blood which then forms other compounds that may be waste or useful to the body.
