An arterial blood gas (ABG) test is a blood test. It measures the acid-base balance (pH) and the levels of oxygen and carbon dioxide in the blood. It uses blood drawn from an artery. This is where the levels of oxygen and carbon dioxide can be measured before they enter body tissues.
An arterial blood gas test is done to:
A health professional takes a sample of your blood.
Collecting blood from an artery is more painful than collecting it from a vein because the arteries are deeper and are protected by nerves.
Watch closely for changes in your health, and be sure to contact your doctor or nurse call line if you have questions about the test.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
