Secretory IgA Stool Test Kit

Measures secretory IgA in stool — the antibody the gut lining produces as a first line of immune defence.

What this test measures

Secretory IgA concentration in a single stool sample.

Why these markers matter

Secretory IgA is the antibody the mucous membranes produce and release onto their own surface. In the gut, it's part of how the lining manages its relationship with everything passing through. Levels vary with stress, illness and time, and both higher and lower results have several possible explanations. It's a marker that adds context to a wider picture rather than answering a question on its own.
