Order IgA Lab Test | Immunoglobulin A TestingImmunoglobulin A, or IgA, is the most abundant antibody class produced by the body's mucosal tissues. It serves as a first-line defense across the respiratory, gastrointestinal, and genitourinary tracts, where it helps neutralize pathogens and regulate immune responses at barrier surfaces. An IgA lab test measures the concentration of this antibody in the blood, offering a window into mucosal immune activity and overall humoral immune function.
About IgA Lab Test | Immunoglobulin A Testing in Lansing
The IgA test quantifies circulating immunoglobulin A to assess mucosal immune status and screen for conditions that alter antibody production.
IgA exists in two main forms: serum IgA, which circulates in the bloodstream, and secretory IgA, which is found in mucosal secretions such as saliva, tears, and intestinal fluids. The blood test primarily measures serum IgA, though its levels often reflect broader immune system activity. Clinicians may order it when evaluating recurrent infections, chronic gastrointestinal symptoms, or suspected immune deficiencies.
Elevated IgA levels can be associated with respiratory and gastrointestinal infections, malabsorption syndromes, and certain inflammatory or autoimmune conditions. Low IgA levels, by contrast, may indicate selective IgA deficiency, a relatively common primary immunodeficiency that can increase susceptibility to mucosal infections and, in some cases, lead to allergic or autoimmune disorders.
Because IgA results are interpreted alongside clinical history and other laboratory findings, the test is rarely diagnostic on its own. It is often part of a broader immunoglobulin panel that includes IgG and IgM, allowing a more complete picture of immune function. Turnaround time is typically one to three business days, and preparation generally follows the performing laboratory's instructions.
