Abg (Arterial Blood Gas) Test
Medically reviewed by Drugs.com. Last updated on May 4, 2025.
An ABG test measures how well your lungs bring oxygen into your blood and get rid of carbon dioxide. An ABG test also measures the acid-base (pH) balance in your blood. The results from the test are used to check if treatments, such as oxygen, are working. The amount of oxygen that you receive depends on your test results. The results also show imbalances in pH that can happen with kidney failure or heart disease. Your healthcare providers will use the results from this test, along with other tests and exams, to treat your conditions.
