What does it mean to have high immunoglobulin A levels?

High immunoglobulin A (IgA) levels may indicate an ongoing immune response, often due to infections, chronic inflammatory diseases, or autoimmune disorders. Elevated IgA can also be associated with conditions like liver disease or certain allergic responses. In some cases, it may not signify a health issue but rather a normal variation in immune function. It's important to interpret high IgA levels in the context of other clinical findings and symptoms.
