Order IgA Lab Test | Immunoglobulin A TestingImmunoglobulin A, or IgA, is the antibody class that predominates in mucosal secretions such as tears, saliva, and the lining of the respiratory and gastrointestinal tracts. An IgA lab test measures the amount of this immunoglobulin in the blood, giving a broad view of humoral immune activity at the body's surfaces.
About IgA Lab Test | Immunoglobulin A Testing in Frederick
IgA testing is typically ordered when a clinician suspects an immune deficiency, an inflammatory condition, or an abnormal response involving the mucosal immune system.
IgA exists in two main forms: serum IgA, which circulates in the bloodstream, and secretory IgA, which is found in mucosal secretions and helps neutralize pathogens at entry points. A blood test primarily reflects the serum fraction, though changes in serum IgA can accompany conditions that also affect mucosal immunity.
Elevated IgA levels may be associated with respiratory and gastrointestinal infections, malabsorption, chronic liver disease, and certain autoimmune or inflammatory disorders. Low IgA levels, by contrast, can indicate selective IgA deficiency or other primary immunodeficiencies, and may also occur with certain medications or protein-loss conditions.
Because IgA results are interpreted alongside symptoms, medical history, and other laboratory findings, a single value rarely provides a diagnosis on its own. Clinicians often compare results with reference ranges and may order additional immunoglobulin tests, such as IgG and IgM, to complete the picture.
