The Alpha-1 antitrypsin (AAT) test is ordered when a youthful person, usually 40 years of age and under, develop wheezing, bronchitis or a persistent cough, after exertion is short of breath, or there are signs of emphysema. This is particularly true if the patient is a non-smoker, if the damage appears to be in the lower lungs and is not exposed to lung irritants.  

It is recommended that AAT testing is performed when there is a diagnosis of conditions such as: 

  • Hard to treat asthma
  • Emphysema at a young age and there are no risk factors such as smoking
  • Liver disease without an established cause
  • Bronchiectasis, stretched and/or widened airways
  • A skin ailment called panniculitis, an unprecedented complication of AAT insufficiency that is portrayed by red, painful bumps on the skin
