IgA is secreted from mucous membranes of the body (in larger quantities than any other antibody class) to assist with binding to foreign organisms and particles, to prevent their potential transport into the body, where they could cause tissue harm and inflammation.

However it should be noted that IgA does not activate the Complement cascade in the way that IgG antibodies do, and therefore IgA specific antigens will often not yield easily identifiable short term inflammatory symptoms (hence sometimes being referred to as ‘silent inflammation’), making laboratory analyses often essential to detecting their presence and potential progression to IgG sensitivities if not identified, and any immune disturbances or compromised mucous membranes (e.g. GIT) are addressed.
