Alpha-1 Antitrypsin Deficiency (AATD)
The diagnosis of alpha-1 antitrypsin deficiency is based on a series of laboratory tests. Testing involves a routine serum alpha-1 antitrypsin test and in cases where a low serum level is detected, additional confirmatory testing (genotyping, phenotyping, sequencing) is required to identify and characterize the presence and severity of the genetic deficiency. Confirmatory testing is widely available to all Canadian physicians. Due to some of the regional differences of the requisition process the following information will be specific to each province.
