AAT blood level test:This test measures the amount of AAT protein found in a sample of blood to see if AAT levels are abnormal. AAT phenotype test:This test checks for the presence of abnormal forms of the AAT protein in the blood. A technical name for this type of testing is isoelectri...
(4) Since establishing the diagnosis is both easy (a simple blood test for a serum level and, if low, a phenotype to secure the diagnosis) and relatively inexpensive (less than $US200 for a serum level or a phenotype in most commercial laboratories...
The finding is recorded of typical a1-antitrypsin globules, confirmed by immunofluorescence and immunoperoxidase methods, in the hepatocytes of a patient shown to have a normal serum antitrypsin level and normal phenotype (TiM) for a1-antitrypsin. The identification of such globules can no longer be...
Alpha-1-antitrypsin deficiency (AATD) is a rare genetic disorder associated with the development of liver and lung disease. AAT is a 52-kD glycoprotein, produced mainly by hepatocytes and secreted into the blood. Agglomeration of the AAT-protein in hepatocytes can result in liver disease. Exposur...

One such case was reported in a 13-year-old with a Pi ZZ phenotype. Although rare, reports have clearly documented the occurrence of emphysema in Pi Null-Null individuals in their twenties. Children, adolescents, and adults with severe AAT deficiency may also have a history of asthma. In ...
How many of the patient with abnormal allele will actually develop the liver disease according to the phenotype? More than 90 phenotypic variants of alpha1-antitrypsin deficiency have been identified, but one phenotype, PiZZ, is responsible for nearly all cases of AAT deficiency emphysema and liver...
NP cells are rounded, “chondrocyte-like” morphology; however, it has distinct phenotype and characteristics compared with chondrocytes [5]. α1-antitrypsin (AAT) was discovered in the mid-1950s but only came to prominence in 1963. It was identified as a potent serine protease inhibitor [6]...
