An arterial blood gas (ABG) test is a detailed test that helps measure how well your lungs are working. It provides important information about how much oxygen is in your blood, how effectively carbon dioxide is being removed, and how your body is maintaining a healthy balance. The test is done using a small blood sample taken from an artery in your wrist, and it is often ordered when your doctor needs a more complete understanding of your breathing and overall respiratory function.
ABG testing is also commonly used for home oxygen qualification and re-qualification, including requirements related to AADL guidelines and funding.
Why it's Ordered
An ABG may be ordered to help your doctor:
• Better understand more complex or unexplained breathing symptoms
• Measure oxygen and carbon dioxide levels accurately
• Monitor chronic lung conditions such as COPD or more advanced respiratory disease
• Assess respiratory status before surgery or certain medical treatments
• Support decisions around oxygen therapy or ventilation needs
• Support home oxygen qualification or re-qualification, including AADL requirements
What to Expect
A small blood sample will be taken from an artery in your wrist by a specially trained healthcare professional. You may feel a brief pinch, pressure, or discomfort during the sample collection, but the procedure is usually quick. After the sample is taken, firm pressure will be applied to the area for several minutes to reduce bruising and help the site heal well.
Your sample is analyzed on-site, and results are typically available within minutes. Our team will explain what’s happening as we go and ensure you feel supported throughout the process.

Mini FAQ
Where is the sample taken from?
At our clinic, ABG samples are taken from an artery in your wrist.
How long does the test take?
The blood draw itself is usually very quick, and results are typically available within minutes because the sample is analyzed on-site.
Does an ABG hurt?
Most patients feel a brief pinch and some pressure. It can be uncomfortable, but it is usually over quickly. Our staff are highly trained and will do everything possible to keep you comfortable.
Will I bruise afterward?
Some mild bruising or tenderness can happen, especially at the wrist. Applying firm pressure afterward helps reduce bruising, and we will guide you on how to care for the area.
Why is pressure applied afterward?
Because the sample comes from an artery, pressure is applied for several minutes to help prevent bruising and ensure the site seals properly.
Why is ABG testing used for home oxygen qualification?
ABG results provide the oxygen measurements required for home oxygen qualification or re-qualification. AADL sets the eligibility requirements for oxygen funding, including when ABG testing is needed and how often it must be repeated.
Our team will guide you through each step and ensure you feel comfortable and supported throughout your visit.
