The DNA Lung Function Test is a comprehensive genetic panel designed to assess your inherited risk for several major respiratory and pulmonary conditions. It evaluates six key traits that influence how your lungs perform under stress, your susceptibility to chronic lung diseases, and your ability to respond to respiratory infections. By analyzing your DNA, the test provides insights that help you take proactive steps to protect your breathing health for the long term.

The test screens for Chronic Obstructive Pulmonary Disease (COPD), pulmonary tuberculosis, pulmonary fibrosis, emphysema, acute respiratory distress syndrome (ARDS), and alpha-1 antitrypsin (AAT) deficiency. These conditions range from structural lung disorders to inflammation-based diseases and genetic protein deficiencies that impair respiratory efficiency.

One of the key markers assessed is your risk for COPD, a progressive disease characterized by airflow limitation and chronic inflammation. This condition, often linked to smoking or pollutants, includes emphysema and chronic bronchitis. Genetic predisposition to COPD helps you understand whether you need more aggressive prevention — even if you’ve never smoked.

The test also checks for AAT deficiency, a genetic condition that lowers the levels of a protective protein in your lungs, raising your risk for emphysema and liver disease. If your results show low AAT activity, you can consider early interventions like respiratory therapy and protective lifestyle changes.

Other traits such as pulmonary fibrosis and ARDS are assessed to determine your lung tissue’s vulnerability to scarring or inflammation during injury or infection. These insights are especially valuable if you work in high-risk environments, have a history of respiratory infections, or are preparing for surgery or anesthesia.

The test also screens for pulmonary tuberculosis, identifying whether your genes make you more susceptible to infection by Mycobacterium tuberculosis. This helps guide appropriate screening, vaccination, or immune support strategies — especially for those living in or traveling to TB-prevalent regions.

Each condition includes a polygenic risk score (PRS), giving you a low, moderate, or high-risk interpretation. Paired with practical, actionable recommendations, this test enables you to build a personal respiratory health plan.

Whether you have a family history of lung disease or simply want to protect your future, the DNA Lung Function Test offers clarity and control over your respiratory wellbeing.
