Order IgA Lab Test | Immunoglobulin A TestingImmunoglobulin A, or IgA, is the antibody class that predominates in secretions such as saliva, tears, and the mucus lining the respiratory and gastrointestinal tracts. An IgA lab test measures the amount of this immunoglobulin in the blood, giving clinicians a view of one arm of the immune system that is often assessed alongside other antibody classes.
About IgA Lab Test | Immunoglobulin A Testing in Elizabeth
IgA testing is used to evaluate humoral immunity and to investigate conditions associated with abnormal IgA production.
IgA exists in two main forms: serum IgA, which circulates in the blood, and secretory IgA, which is found on mucosal surfaces and helps neutralize pathogens before they penetrate tissue. Because IgA is produced by plasma cells in mucosal-associated lymphoid tissue, changes in its level can reflect activity in the respiratory, digestive, and other mucosal systems.
A total IgA measurement is frequently ordered as part of a broader immunoglobulin panel that includes IgG and IgM. Results are interpreted in the context of the patient's age, clinical history, and other laboratory findings, since reference intervals vary between laboratories and populations.
Elevated IgA levels have been associated with certain respiratory and gastrointestinal infections, inflammatory conditions, and malabsorption disorders. Low IgA, by contrast, may point to selective IgA deficiency or other immune deficiencies, and can also be relevant when evaluating reactions to blood products.
