Human Immunoglobulin A (IgA) represents about 15% to 20% of immunoglobulins in the blood, although it is primarily secreted across the mucosal tract into the stomach and intestines. This prevents microbes from binding to epithelial cells in the digestive and respiratory tracts.

Human Immunoglobulin A (IgA) helps to fight against pathogens that contact the body surface, are ingested, or are inhaled. Human Immunoglobulin A IgA antibodies are secreted mainly by mucosal lymphoid tissues.
