Used to diagnose hereditary hypo α1-antitrypsin (α1AT). An increased prevalence of non-MM phenotypes is found with cryptogenic cirrhosis and with CAH. Cirrhosis in a child should raise consideration of α1AT deficiency or Wilson's disease. Diagnosis of inflammatory states, if elevated (eg, rheumatoid arthritis, bacterial infection, vasculitis, neoplasia). Alpha 1-antitrypsin or α1-antitrypsin (A1AT) is a serine protease inhibitor (serpin). It protects tissue from enzymes from inflammatory cells, especially elastase, and is present in human blood at 1.5 - 3.5 gram liter.
