| Note: |
Alpha-1-antitrypsin serum protein concentration determination and A1A genotyping are performed on all specimens. If two deficiency alleles (ZZ, SZ, or SS) are detected, then testing is complete. If the protein concentration is less then 100 mg/dL and only one or no deficiency allele is detected by A1A genotyping, then phenotyping will be performed.
