Brief Description
Immunoglobulins are the most important part of the humoral immune system of the organism. Of clinical interest are immunoglobulin deficiencies and increased levels of the immunoglobulins. Changes in serum immunoglobulin concentrations can be classified as follows:
Hypogammaglobulinemias: Individuals with secretory IgA deficiency are found to suffer more commonly from mucosal infections, atopy, and autoimmune diseases. Individuals with absent IgA have a higher than expected incidence of rheumatic disorders and lymphoma. Polyclonal gammopathies: Increased levels occur in chronic liver disease, chronic infections, especially of the gastrointestinal and respiratory tracts, neoplasia of the lower gastrointestinal tract, inflammatory bowel disease, some immunodeficiency states such as Wiskott-Aldrich syndrome and rheumatoid arthritis. Monoclonal gammopathies: IgA multiple myeloma , Immunoturbidimetric test for the quantitative determination of immunoglobulin A (IgA) in human serum.
