About Alpha 1 antitrypsin stool test
What is alpha-1 antitrypsin?
Alpha-1 antitrypsin (AAT) is a protein produced by the liver which travels in the blood to protect tissues from the body’s own immune system. AAT has a particularly important function in the lungs where it reduces the activity of an enzyme responsible for breaking down proteins. The activity of this enzyme must be controlled to prevent damage to the lungs.
AAT can be used to measure protein leakage from serum into the gut as it simply passes through the gut without being reabsorbed or degraded by the gut. Abnormal protein leakage occurs in disorders such as protein-losing enteropathy (PLE).
Why take the test?
This stool test measures faecal excretion of AAT and can be used to help PLE.
