In blood test results, the IEF results are notated as, e.g., PiMM, where Pi stands for protease inhibitor and "MM" is the banding pattern of that person. [citation needed] Other detection methods include use of enzyme-linked-immuno-sorbent-assays in vitro and radial immunodiffusion. Alpha-1 antitrypsin levels in the blood depend on the genotype.
Alpha-1 antitrypsin or α 1-antitrypsin (A1AT, α 1 AT, A1A, or AAT) is a protein belonging to the serpin superfamily. It is encoded in humans by the SERPINA1 gene.A protease inhibitor, it is also known as alpha 1 –proteinase inhibitor (A1PI) or alpha 1-antiproteinase (A1AP) because it inhibits various proteases (not just trypsin). [5]
The alpha-1 fraction does not disappear in alpha 1-antitrypsin deficiency, however, because other proteins, including alpha-lipoprotein and orosomucoid, also migrate there. As a positive acute phase reactant, AAT is increased in acute inflammation. [citation needed] Bence Jones protein may bind to and retard the alpha-1 band. [citation needed]

Blood test results should always be interpreted using the reference range provided by the laboratory that performed the test. ... Alpha 1-antitrypsin (AAT) 20, [159 ...
Different methods of quantifying protein loss in the bowel include faecal excretion of alpha 1-antitrypsin, a marker of protein losing enteropathy, as well as viral serologies, which may be useful to determine the cause of the PLE. [1] Alpha 1-antitrypsin is a blood protein that is lost in the gut, however, it is not actively secreted or ...
PAS diastase stain is also used to identify alpha-1 antitrypsin globules in hepatocytes, which is a characteristic finding of alpha-1 antitrypsin deficiency. [2] PAS diastase stain is also used in diagnosing Whipple’s disease , as the foamy macrophages that infiltrate the lamina propria of the small intestine in this disease possess PAS ...
John W. Walsh (February 4, 1949 – March 7, 2017) was an American non-profit leader and patient advocate.After being diagnosed with alpha-1 antitrypsin deficiency, he co-founded the Alpha-1 Foundation and AlphaNet, both of which serve people diagnosed with that condition, and the COPD Foundation, which serves people with chronic obstructive pulmonary disease.
