In one version of this testing, you provide a blood sample by pricking your finger and placing a drop of blood on special test paper. This test paper is then sent to a laboratory in a prepaid envelope. The laboratory conducts AAT genotype testing, and the results are provided confidentially ...

Alpha-1-AT deficiency is associated with chronic obstructive lung disease (emphysema) and less frequently with hepatic cirrhosis in infants and respiratory distress of the newborn. Increase in alpha-1-AT occurs as an acute phase response to tissue necrosis and inflammation. ...
1,5 AAT diffuses from the blood into tissues, where interstitial concentrations are lower due to the presence of tissue barriers to diffusion. AAT is only minimally transported across the placenta, and the Pi type of the cord serum is that of the fetus rather than the mother. AAT is an ...
Definition (NCI) A genetic disorder characterized by decreased alpha-1 antitrypsin activity in the lungs and blood and deposition of alpha-1 antitrypsin protein in the hepatocytes. These abnormalities result from defective production of alpha-1 antitrypsin and lead to the development of emphysema, cirr...

A glycoprotein that is abundant in the blood plasma of human and other mammalian fetuses and is also present in the serum of people with certain diseases, such as liver cancer. Abnormal levels in maternal serum are associated with certain fetal abnormalities, including Down syndrome and spina bifi...
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...

Alpha1-antitrypsin deficiency (AATD) was first described by Laurell and Eriksson in 1963. Laurell noted the absence of the band of alpha1- protein in 5 of 1500 serum protein electrophoreses (SPEP) submitted to his laboratory in Sweden.
