HIGH LGA TEST RESULT REFERENT VALUES FOR ADULTS. What does high IgA test result referent values for adults level mean?

Upper limit of normal IgA test result referent values for adults is 560(mg/dl).

IgA is found in high concentrations in the body's mucous membranes, particularly the respiratory passages and gastrointestinal tract, as well as in saliva and tears.

IgA also plays a role in allergic reactions. Its levels rise in response to the presence of allergens, such as pet dander, in sensitive people. IgA levels also may be high in autoimmune conditions, disorders in which the body mistakenly makes antibodies against healthy tissues.
