Arterial Blood Gas (ABG)
An arterial blood gas (ABG) test measures the oxygen and carbon dioxide levels in your blood as well your blood's pH balance. The sample is taken from an artery, not a vein, and healthcare providers typically order it in certain emergency situations.
What is an arterial blood gas (ABG) test?
An arterial blood gas (ABG) test is a blood test that requires a sample from an artery in your body to measure the levels of oxygen and carbon dioxide in your blood. The test also checks the balance of acids and bases, known as the pH balance, in your blood.
Your body normally tightly regulates the amount of oxygen and carbon dioxide in your blood, because low blood oxygen levels (hypoxemia) can lead to many serious conditions and damage to individual organ systems, especially your brain and heart.
Arterial blood gas tests can help healthcare providers interpret conditions that affect your respiratory system, circulatory system and metabolic processes (how your body transforms the food you eat into energy), especially in emergency situations.
There’s also a test known as a "blood gas analysis," which uses a sample of blood from anywhere in your circulatory system (artery, vein or capillary). An arterial blood gas (ABG) test only tests a blood sample from an artery in your body.
Other common names for an arterial blood gas test include:

What is measured in an arterial blood gas test?
An arterial blood gas test usually includes the following measurements:
Oxygen content (O2CT): This measures the amount of oxygen in your blood.
Hemoglobin: This measures the amount of hemoglobin, the protein responsible for carrying oxygen to your cells, in your blood.
Oxygen saturation (O2Sat): This measures how much hemoglobin in your blood is carrying oxygen. Hemoglobin is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body.
Partial pressure of oxygen (PaO2): This measures the pressure of oxygen dissolved in your blood. It helps show how well oxygen moves from your lungs to your bloodstream.
Partial pressure of carbon dioxide (PaCO2): This measures the amount of carbon dioxide in your blood and how well carbon dioxide can move out of your body.
pH: This measures the balance of acids and bases in your blood, known as your blood pH level. The pH of blood is usually between 7.35 and 7.45. If it’s lower than that, your blood is considered too acidic. If it’s higher than that range, your blood is considered too basic (alkaline).
Bicarbonate (HCO3): This is calculated using the measured values of pH and PaCO2 to determine the amount of the basic compound made from carbon dioxide (CO2.)
