Figure 2 Proposed algorithm for α-1 antitrypsin (AAT) deficiency testing. In this algorithm, individuals with low serum AAT are evaluated by targeted testing. If the results explain the serum level, then the result can be reported and no further testing is required. If the results do not explain the serum level, then sequencing of the entire coding regions of SERPINA1 may identify deleterious alterations responsible for AAT deficiency. Also, for individuals with normal isoelectric focusing (IEF) results and low serum AAT, sequencing of the coding region of SERPINA1 can be diagnostically helpful.
