|Processing notes||Refrigerate. Order Quest Test # 853X Alpha-1-Antitrypsin Phenotyping|
|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.
