Immunoglobulin A, or IgA, is the most abundant antibody class produced by the body's mucosal surfaces, where it helps defend the respiratory, digestive, and genitourinary tracts. An IgA lab test measures the amount of this antibody in the blood, giving clinicians a window into immune function at those barrier sites.

About IgA Lab Test | Immunoglobulin A Testing in Orange

The IgA test is a straightforward blood draw that quantifies immunoglobulin A, one of the five major classes of antibodies.

IgA exists in two main forms: serum IgA circulating in the bloodstream, and secretory IgA found in saliva, tears, and mucosal secretions. The blood test primarily reflects the serum fraction, though abnormal results can point to broader immune or mucosal issues.

Elevated IgA levels are sometimes associated with chronic respiratory or gastrointestinal infections, inflammatory conditions, and malabsorption syndromes. Low levels may indicate selective IgA deficiency, a relatively common primary immunodeficiency that can affect susceptibility to certain infections and reactions to blood products.

Because IgA results are interpreted alongside symptoms, medical history, and other laboratory findings, the test is rarely diagnostic on its own. Clinicians use it to support or rule out conditions, monitor known immune disorders, or investigate recurrent infections.
