IgA Immunoglobulin Total

The IgA Immunoglobulin test is used to measure the levels of Immunoglobulin A, an antibody that plays a critical role in your immune defense, particularly within the mucous membranes of the respiratory and digestive tracts. Getting this test is incredibly helpful because it can identify the root cause of recurrent infections, unexplained chronic diarrhoea, or inflammatory bowel issues. By detecting an IgA deficiency or an overabundance, healthcare providers can diagnose underlying conditions such as celiac disease, autoimmune disorders, or certain types of cancers (like multiple myeloma). Essentially, it acts as a focused security check on the first line of defense for your body, ensuring your mucosal immunity is robust enough to ward off pathogens.
