 Alpha-1 Antitrpsin testing may be ordered when a person under 40 years of age develops a chronic cough or bronchitis, wheezing, or short of breath after exertion and/or shows other signs of emphysema. This is especially true when the patient has not be exposed to know lung irritants, is not a smoker, and when the lung damage appears to be located low in the lungs.  AAT testing may also be done if you have a close relative with alpha-1 antrypsin deficiency.

The American Thoracic Society recommends AAT testing when individuals are diagnosed with certain conditions such as:

  • Emphysema at a young age (younger than 45 years old) and/or no obvious risk factors for the disease, such as smoking
  • Bronchiectasis, a condition in which the airways are stretched and/or widened
  • Asthma that is difficult to treat
  • Liver disease with no known cause
  • A skin disease called panniculitis, an uncommon complication of AAT deficiency that is characterized by red, tender nodules on the skin
