A high level of immunoglobulin A in the blood is indicative of a possible autoimmune disease, such as rheumatoid arthritis or systemic lupus erythematosus, according to WebMD. IgA immunoglobulins protect body surfaces that are exposed to the environment and therefore to foreign organisms. Pinching AJ: Laboratory investigation of secondary High IgA levels are also associated with liver diseases, such as chronic hepatitis or cirrhosis, and multiple myeloma.

This is true regardless of age, sex, duration of disease, and type of treatment (insulin/diet or oral hypoglycemic agents and/or diet). In Clinics in Immunology and Allergy. 447-468, 2. Recent important studies have shown that immunodeficient patients lacking IgA (IgAD, IgA/IgG subclass, and CVID) with a high titre of anti-IgA antibodies can be given low IgA IVIG (270 mg/litre and 790 mg/litre) repeatedly, with no adverse effects. IgA antibody levels thus dropped to about half the titer at the peak response, following the first dose. This is why doctors often also test for serum total IgA. Clin Immunol Newsletter 1990;10:84-86. High IgA levels and low IgM levels associate together For subjects with high IgA, there is a greater proportion of subjects with low IgM relative to subjects with elevated IgM (10 of 107, 9%; vs 5 of 107, 5%; P = .0001). polyclonal or oligoclonal immunoglobulin proliferation in hepatic Some include First Aid Cards, Foreign Language Exploratory, and German 1 (high school credit), Yearbook, and Video Production. immunodeficiency.
