CO2 Blood Test - More Information

The carbon dioxide test, also known as a CO2 lab test, measures the CO2 blood level.

Carbon dioxide (CO2) is produced in large quantities by the human body as a product of cellular respiration. With every respiration, carbon dioxide removed from the body. In the blood, carbon dioxide exists in the bicarbonate (HCO3) form. In this form, carbon dioxide plays a role as a buffer that helps stabilize the acid/base balance in the body. Additionally, high carbon dioxide levels in the blood are a signal to the respiratory centers in the brain that help regulate the pace of respiration. The target CO2 pressure in the blood is thought to be 40 mm of Hg.

To get a CO2 blood test near you, just order online and get your blood drawn at the Quest Diagnostics lab. Once your CO2 lab test report is ready, it will be available for download. As can be seen on the sample CO2 lab results above, the carbon dioxide blood level is reported as a number which can be compared against the reference range provided by the lab.
