Total IgA testing is used for immune deficiency disorders such as allergy and gluten sensitivity.
Immunoglobulins play a critical role in the body’s immune response.
IgA makes up approximately 15% of the total serum immunoglobulins. IgA is present in saliva, tears, respiratory and gastric secretions, and breast milk. IgA provides protection against infection in the mucus membranes of the body such as the respiratory tract and the gastrointestinal tract. When passed from mother to baby during breast-feeding, it helps protect the infant’s gastrointestinal tract. Generally, only a low level of IgA may be present in the body after 6 months of age, however IgA levels increase with age.
