The Immunoglobulin A (IgA), Total test measures the level of IgA antibodies in the blood. IgA plays a key role in immune defense, particularly in mucosal surfaces such as the respiratory and gastrointestinal tracts.
This test is commonly used to evaluate immune system function and may help identify immune deficiencies, chronic infections, or autoimmune conditions. Total IgA testing is also important when interpreting certain antibody tests, such as celiac disease screening, where IgA deficiency can affect results.
