Indications for diagnostic testing for AAT deficiency (AATD) as per the American Thoracic Society and the European Respiratory Society are as follows [5, 17] :

  • Symptomatic adults with emphysema, chronic obstructive pulmonary disease (COPD), or asthma with airflow obstruction that is incompletely controlled after aggressive treatment with bronchodilators
  • Individuals with unexplained liver disease, including neonates, children, adults, and older adults
  • Asymptomatic individuals with persistent obstruction on pulmonary function tests (PFTs) with or without identifiable risks factors (eg, smoking, occupational exposure)
