Alpha-1 antitrypsin (AAT) is a protein primarily produced by the liver that helps protect the lungs and other organs from enzymes that cause inflammation. Measuring AAT levels in faeces can help detect intestinal protein loss and inflammation, assisting in the diagnosis of gastrointestinal conditions such as inflammatory bowel disease and protein-losing enteropathy.

Individuals with chronic diarrhea, abdominal pain, or unexplained weight loss could benefit from fecal Alpha-1 Antitrypsin testing. It’s particularly useful for diagnosing conditions that cause protein loss through the gut, such as inflammatory bowel disease (IBD) or protein-losing enteropathy. This test helps in assessing the severity of intestinal inflammation and monitoring treatment efficacy.
Alpha-1 Antitrypsin levels in the blood reflect the protein’s overall production and its role in systemic inflammation and lung protection. Elevated blood levels can indicate liver or lung disorders. In contrast, fecal alpha-1 antitrypsin levels specifically indicate protein loss or inflammation in the gastrointestinal tract, helping diagnose conditions affecting intestinal health.
Elevated levels of Alpha-1 Antitrypsin indicate an inflammatory irritation of the intestinal mucosa. This can lead to a decrease in the absorption of nutrients from food. There is often a link between elevated Alpha-1 Antitrypsin levels and an increased permeability of the intestinal mucosa, which in turn can lead to an increased load on the body’s systemic defense system.
Alpha-1 Antitrypsin (AAT) is closely linked to the health of the intestinal mucosa. It protects the mucosal lining from damage by inhibiting harmful enzymes during inflammation. Elevated levels of AAT in feces can indicate intestinal inflammation, such as in inflammatory bowel disease, and suggest increased intestinal permeability, or “leaky gut.” Additionally, high fecal AAT levels may point to protein-losing enteropathies, where the integrity of the intestinal mucosa is compromised, leading to protein loss. Essentially, AAT serves as a key biomarker for assessing the condition and health of the intestinal mucosa.
GetTested’s Gut Microbiome Test Large is the test for you who want a comprehensive overview of your gut health. Many health problems arise from imbalances in our gut and this test is an in-depth analysis of your gut by measuring the presence of bacteria, yeast, the pH of the stool and digestive functions, such as pancreatic elastase, bile acids, digestive residues, as well as alpha-1 antitrypsin, calprotectin and secretory IgA.
