Intestinal Bacteria IgA IgM Leaky Gut


The Immunobilan test is an antibody screening assay for antibodies (IgA and IgM) directed against antigens from intestinal pathogens. IgA are secreted from intestinal cells, IgM are produced by immune cells in the blood. In healthy individuals pathogenic bacteria are only found in low quantities in the gut, and antibody titers in the blood are very low. In case of bacterial overgrowth however, large quantities of IgA are produced and some IgA will be found in the bloodstream. In case of leaky gut, bacterial proteins may make their way to the bloodstream, and specific IgM will be produced. Therefore, high titers of IgM for intestinal bacteria is an indicator of increased intestinal permeability. All Immunobilan bacteria are strictly associated with the gut, with the exception of Klebsiella, which is also associated with respiratory and urinary tract infections.

Detection of IgA/IgM directed against Klebsiella pneumoniae, Pseudomonas aeruginosa, Citrobacter koseri, Pseudomonas putida, Morganella morganii, Hafnia alvei
