About the Test

The Total Immunoglobulin A (IgA) test measures the concentration of IgA, a type of antibody that plays a crucial role in the immune system by protecting mucosal surfaces, such as those in the respiratory and gastrointestinal tracts. This test is used to assess immune system function and diagnose conditions related to IgA deficiencies or excesses.
