IMMUNOGLOBULIN-A (IgA)

Immunoglobulin A (IgA) is a crucial antibody blood protein essential for immune defense. IgA deficiency, signifying low or absent levels in the blood, impacts mucous membranes in the respiratory and digestive tracts, as well as saliva, tears, and breast milk. This deficiency has been linked to conditions like asthma, allergies, and autoimmune health problems, where the immune system erroneously attacks the body. Understanding the role of IgA sheds light on its importance in fostering a robust and balanced immune response.
