Order IgA Lab Test | Immunoglobulin A TestingImmunoglobulin A, or IgA, is an antibody class that plays a central role in mucosal immunity, guarding the surfaces of the respiratory and gastrointestinal tracts.

About IgA Lab Test | Immunoglobulin A Testing in Cerritos
The IgA test is a serologic measurement used to assess the concentration of immunoglobulin A in serum.
IgA is the most abundant antibody produced by the body on a daily basis and is the predominant immunoglobulin in secretions such as saliva, tears, and intestinal fluids. Its primary function is to neutralize pathogens and toxins before they can penetrate mucosal surfaces.
Serum IgA testing is typically ordered when a clinician suspects an immune deficiency, an autoimmune process, or a chronic mucosal condition. Elevated IgA levels can be associated with respiratory and gastrointestinal infections, malabsorption disorders, and certain inflammatory conditions. Low levels may point toward selective IgA deficiency or other immune dysregulation.
Because IgA results are interpreted alongside clinical history, symptoms, and sometimes other immunoglobulin measurements, the test is rarely diagnostic on its own. Reference ranges vary by laboratory method, and a physician evaluates the numeric result in the context of the individual patient.
