Background Information
Immunoglobulin A (IgA) is a crucial antibody that plays a pivotal role in the immune system's first line of defense, primarily safeguarding the body's mucosal surfaces-such as the respiratory, gastrointestinal, and urogenital tracts. As the second most abundant isotype in human serum and the dominant antibody found in external secretions like saliva, tears, and breast milk, IgA specialized in neutralizing pathogens, preventing toxins and microbes from adhering to epithelial cells, and maintaining a healthy balance with the body's natural microbiota.
