Diagnosis of AAT def: Alpha-1-antitrypsin is a protease inhibitor of the enzyme elastase. Deficiency can result in disease of the lung, liver, and skin. The serum level is quantified in the diagnosis of aat deficiency. If the aat serum level is greater than 80 mg/dl, it is unlikely that the patient has clinically significant aat deficiency.
