What Can a Blood Test Reveal About COPD?
Understanding how blood tests can help assess COPD and guide treatment
Blood tests can provide important information about how COPD is affecting the body and, in some cases, help clinicians make treatment decisions. Different types of blood tests provide different information.
In this video, Prof. Dr. Wim Janssens explains the difference between a regular venous blood test and an arterial blood gas test, what each test can reveal, and when they may be useful in COPD care.
In this video, you’ll learn:
- What a regular blood test can reveal
- How eosinophil levels may help guide inhaled corticosteroid treatment
- What an arterial blood gas test can tell us
- How oxygen and carbon dioxide levels provide information about gas exchange
- How blood gas measurements can help understand exercise limitations
- When results may indicate a need for oxygen therapy
- What to expect from these tests and whether preparation is needed

What blood tests are used in COPD?
A standard blood test uses blood taken from a vein and can provide information such as your eosinophil level. This may be useful when clinicians are considering certain treatments for COPD.
An arterial blood gas test measures oxygen and carbon dioxide levels in the blood. It can provide information about how effectively the lungs are exchanging gases and may be particularly useful in people with more advanced COPD.
Why are blood tests useful?
Blood test results can add important information to other assessments used in COPD. They can help clinicians understand how your lungs are functioning, assess your individual needs and, where appropriate, guide treatment decisions.
