The Carbon Dioxide (CO₂) test measures the level of carbon dioxide in the blood, which reflects the body’s acid–base (pH) balance and electrolyte status. Most of the CO₂ measured in the blood is in the form of bicarbonate, a key buffer that helps maintain normal blood pH.
This test is commonly used to assess metabolic and respiratory function and may help evaluate kidney disease, lung disorders, dehydration, or conditions that affect acid–base balance. It is often ordered as part of a basic or comprehensive metabolic panel.
