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.
