Could a Blood Test Reveal the Cause of Your COPD? Alpha-1 Antitrypsin Deficiency
Understanding an inherited condition that can increase the risk of COPD and emphysema
Not all COPD has the same underlying cause. Alpha-1 antitrypsin deficiency (AAT deficiency) is a rare inherited condition that can increase the risk of developing COPD and lung emphysema, sometimes at a younger age than usual.
In this video, Prof. Dr. Stephanie Everaerts explains what alpha-1 antitrypsin deficiency is, how it can affect the lungs and liver, and why identifying the condition can be important for patients and their families.
In this video, you’ll learn:
- What alpha-1 antitrypsin deficiency is and how it is inherited
- How low levels of alpha-1 antitrypsin can affect the lungs
- Why smoking can increase the risk of lung damage
- How a blood test can help identify the condition
- Why diagnosis may also be important for family members
Watch the video below to learn more about alpha-1 antitrypsin deficiency and why recognising this rare genetic condition matters.
What is alpha-1 antitrypsin deficiency?
Alpha-1 antitrypsin is a protein that helps protect the lungs from damage. In people with alpha-1 antitrypsin deficiency, the body does not produce enough functional alpha-1 antitrypsin, which can increase the risk of lung disease.
The condition is inherited, meaning it can be passed from parents to their children. It can also affect the liver in some people.
Why is testing important?
Because alpha-1 antitrypsin deficiency is inherited, identifying it can help explain why someone has developed COPD or emphysema, particularly when lung disease occurs at a younger age.
A blood test can measure alpha-1 antitrypsin levels and help identify people who may have the condition. If a diagnosis is made, testing and assessment of family members may also be considered.
