Secretory IgA feces

The secretory IgA feces test is a laboratory analysis used to measure the level of secretory immunoglobulin A (IgA) in a stool sample. This test is an important tool in assessing the local immune response in the gastrointestinal tract. IntroLab in Belgrade is dedicated to providing accurate and reliable results using the latest methods and top-notch equipment.

Significance of the secretory IgA feces test

Secretory IgA is a type of antibody found in the mucosa of the gastrointestinal tract. It plays a crucial role in protecting the mucosa from infections, neutralizing harmful agents, and helping maintain the balance of microorganisms. The secretory IgA feces test allows for the measurement of secretory IgA levels in the stool, providing insight into the local immune response in the intestines.

Indications

The secretory IgA feces test is used in the diagnosis and monitoring of various gastrointestinal disorders. This analysis is used to:

• Assess inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis.
• Identify gastrointestinal tract infections, such as bacterial, viral, or parasitic infections.
• Evaluate allergic reactions, especially in children.
• Monitor responses to therapy or diet in certain conditions, such as gluten or lactose intolerance.

Sample collection and analysis

Collecting a stool sample for the secretory IgA feces analysis is usually done at home or in a laboratory, using special containers that ensure hygienic conditions. Patients are provided with detailed guidelines on the sample collection procedure. After collection, the sample is carefully prepared and subjected to specific processing procedures to isolate the secretory IgA. Afterward, IgA levels are quantified using methods such as enzyme-linked immunosorbent assay (ELISA) or immunochemical testing.
