About IgA Lab Test | Immunoglobulin A Testing in Orange
Immunoglobulin A (IgA) is one of the five main classes of antibodies produced by the immune system.
IgA is primarily found in mucosal areas, including the respiratory and gastrointestinal tracts, as well as in saliva, tears, and breast milk. It serves as a first line of defense by preventing pathogens from attaching to and penetrating mucosal surfaces.
The IgA Lab Test quantifies the amount of IgA in the blood. Elevated IgA levels can be associated with respiratory and gastrointestinal infections, as well as malabsorption conditions. Conversely, low levels may indicate immunodeficiency disorders.
This test is typically ordered when a healthcare provider suspects an immune disorder or to monitor a known condition affecting IgA levels. Results are interpreted alongside clinical findings and other laboratory tests.
