The data are presented for age groups in geometric means and standard deviations and by modal distribution. Intensity ranges are the cut-offs that define the classes. The prevalence of allergic disease has increased in industrialized countries 1, 2 including Taiwan. Immunoglobulin E (IgE) is one of the 5 classes of immunoglobulins and is defined by the presence of the epsilon heavy chain. The normal or expected concentration of IgE is low compared to other antibody isotypes. and Genetics at Aarhus . After washing away nonspecific IgE, enzyme-labeled anti-IgE antibody is added to form a complex. It is present in a healthy person's serum at extremely low concentrations. Total IgE levels can be affected by many conditions, so total IgE testing by itself does not establish a diagnosis. . These antibodies travel to cells that release chemicals, causing an allergic reaction. The molecular weight of IgE is 190 kDa, which is more than the molecular weight of IgA, IgG, and IgD, i.e. 3.2.
