Order IgA Lab Test | Immunoglobulin A TestingImmunoglobulin A, or IgA, is the antibody class that guards the mucosal surfaces lining the respiratory and digestive tracts.

About IgA Lab Test | Immunoglobulin A Testing in Normal
IgA is one of the five major classes of immunoglobulins and is produced in greater quantity than any other antibody type.
IgA is found in saliva, tears, and the secretions of the respiratory and gastrointestinal tracts, where it helps neutralize pathogens before they can establish an infection.
A blood test for IgA quantifies the total amount of this immunoglobulin circulating in serum. Results are typically interpreted alongside other immunoglobulin measurements, such as IgG and IgM, to build a broader picture of immune status.
Elevated IgA levels have been associated with respiratory and gastrointestinal infections as well as malabsorption. Low levels may also be clinically meaningful, which is why the test is often ordered as part of a panel rather than in isolation.
