Understanding Lab Tests for Emphysema
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Emphysema is a progressive lung disease that is part of chronic obstructive pulmonary disease (COPD). While emphysema is primarily diagnosed through lung function tests and imaging, blood tests play a crucial role in identifying underlying genetic causes that may contribute to the development of this condition.
Recommended Test
Alpha-1-Antitrypsin, Quantitative
This test measures the level of Alpha-1-Antitrypsin, an enzyme that protects the lungs from damage caused by white blood cells. A deficiency of this enzyme allows white blood cells to harm lung tissue, leading to the development of emphysema. Testing is particularly important for individuals who develop emphysema at a young age or have a family history of the condition.

The Role of Blood Testing in Emphysema
Although there is no blood test to directly diagnose emphysema itself, blood testing is fundamental for identifying genetic deficiencies that can predispose individuals to developing emphysema. This information is vital for understanding the underlying cause, assessing risk factors, and guiding appropriate treatment and management strategies.
Why Alpha-1-Antitrypsin Testing Matters
Alpha-1-Antitrypsin Deficiency is a genetic condition that significantly increases the risk of developing emphysema, especially in younger individuals or those with minimal smoking history. Identifying this deficiency helps healthcare providers understand the root cause of emphysema and may influence treatment decisions, family screening recommendations, and lifestyle modifications.
