Question: does high iga blood test mean?
Answer: May mean that IgA monoclonal gammopathy of unknown significance (MGUS) or IgA multiple myeloma is present. Levels of IgA are also higher in some autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus (SLE), and in liver diseases, such as cirrhosis and long-term (chronic) hepatitis.
