Book a Test- Antiphospholipid Antibodies IGA

Immunoglobulin A (IgA) is an antibody that plays a crucial role in mucosal immunity, protecting the body's surfaces, such as the respiratory, gastrointestinal, and genitourinary tracts. IgA is produced by immune cells in mucosal tissues and helps neutralize pathogens, toxins, and allergens. Elevated IgA levels can indicate infections, autoimmune disorders, or allergies, while low levels can increase susceptibility to infections. IgA deficiency is a common primary immunodeficiency, increasing the risk of respiratory and gastrointestinal infections. There are different types of IgA namely Serum IgA, Secretory IgA (sIgA), etc. IgA is the primary antibody responsible for protecting mucosal surfaces, such as the respiratory, gastrointestinal, and genitourinary tracts, from infections. IgA also helps neutralize bacteria, viruses, and other pathogens by binding to them and preventing their attachment to mucosal surfaces.
