Order IgA Lab Test | Immunoglobulin A TestingImmunoglobulin A, or IgA, is an antibody class that plays a central role in mucosal immunity. It is the predominant antibody found in secretions such as saliva, tears, and the fluids lining the respiratory and gastrointestinal tracts. An IgA lab test measures the amount of this immunoglobulin in the blood, offering a quantitative view of one component of the humoral immune response.
About IgA Lab Test | Immunoglobulin A Testing in Goose Creek
The IgA test is a blood-based immunoassay that quantifies circulating immunoglobulin A.
IgA exists in two main forms: monomeric IgA in the bloodstream and secretory IgA at mucosal surfaces. The test typically detects total serum IgA, which reflects the combined contribution of these pools. Because IgA is produced by plasma cells in mucosal-associated lymphoid tissue, its concentration can shift in response to a range of immune and inflammatory conditions.
Clinicians may order an IgA test to evaluate recurrent respiratory or gastrointestinal infections, chronic diarrhea, or suspected malabsorption. Elevated IgA levels have been associated with certain infections, inflammatory disorders, and liver disease. Reduced levels can indicate selective IgA deficiency, a relatively common primary immunodeficiency that may be asymptomatic or linked to increased susceptibility to mucosal infections.
Results are interpreted alongside clinical history, other immunoglobulin measurements such as IgG and IgM, and additional laboratory findings. A single IgA value is rarely diagnostic on its own; trends over time and the broader immunological picture are usually more informative. Specimen collection follows standard venipuncture technique, and the laboratory reports a quantitative result with a reference interval.
