| Normal range | 90% of Normals are MM |
| Synonyms | A1AT; A1-AT; Alpha-1-PI; Alpha-1-Protease inhibiitor; A1-Antitrypsin; A1-PI; A1-Protease inhibitor |
| Stability | Room temperature 8 hours, refrigerated 1 week, frozen at -20C 1 month. |
| Turn around times | Test set up 5x per week, turnaround 5-7 days |
| Additional information | Most normal individuals have the M phenotype (M,M1, or M2). Over 99% of M phenotypes are genotypically MM. In the absence of family studies, the phenotype (M) and quantitative level can be used to infer the genotype MM. The most common alleles associated with a quantitatave deficiency ate Z and S. The reports for the rare alleles will indicate whether or not they have been associated with reduced quantitative levels. |
