About IgA Lab Test | Immunoglobulin A Testing in Normal
The IgA test is a blood test that quantifies immunoglobulin A, an antibody produced by plasma cells.
IgA is one of five major antibody classes, alongside IgG, IgM, IgE, and IgD. It is produced by plasma cells and is particularly concentrated in secretions such as saliva, tears, and mucus, as well as in the bloodstream.
Because IgA is involved in mucosal immunity, abnormal levels can accompany a range of conditions. Elevated IgA may be associated with respiratory and gastrointestinal infections, inflammatory conditions, and malabsorption, while low levels can point to deficiencies in antibody production.
Results are typically interpreted alongside a patient's history, symptoms, and other laboratory findings. A single IgA value rarely provides a complete picture, so clinicians often consider it together with total immunoglobulin levels and specific antibody tests.
