Arterial Blood Gas

If you are having severe breathing problems or your symptoms may be the cause of a lung disease such as asthma, cystic fibrosis or chronic obstructive pulmonary disease (COPD), an arterial blood gas (ABG) test may be performed to reach an accurate diagnosis.

An ABG is a blood test taken from the artery of the arm that is used to evaluate your lung's ability to provide blood with oxygen and remove carbon dioxide. It also measures the pH (acidity) of the blood.

Rated High Performing for Pulmonology by U.S.News & World Report, Jefferson's Division of Pulmonary and Critical Care Medicine physicians deliver comprehensive diagnostic and therapeutic services for diseases that affect the respiratory system.
