About the test

Carbon Dioxide (CO2) in a blood test measures the amount of carbon dioxide in the blood, primarily in the form of bicarbonate. It helps assess the bodyโ€™s acid-base balance and is commonly included in metabolic panels. Abnormal CO2 levels can indicate issues with lung function, kidney function, or metabolic conditions such as acidosis or alkalosis.
