An immunoglobulin E (IgE) test measures the level of IgE, a type of antibody. Antibodies are made by the immune system to protect the body from bacteria, viruses, and allergens. IgE antibodies are normally found in small amounts in the blood, but higher amounts can be a sign that the body overreacts to allergens. Hyper IgE Syndrome (HIES) is a rare primary immunodeficiency disease characterized by eczema, recurrent staphylococcal skin abscesses, recurrent lung infections, eosinophilia (a high number of eosinophils in the blood) and high serum levels of IgE. Most cases of HIES are sporadic, but some familial cases of HIES have been reported, with either an autosomal .
Variations in the upper limit of normal total serum IgE have been reported: they can range from to 1, UI/ml; but the usually accepted upper limit is between and UI/ml. In this study we measured the total serum IgE levels (RIST-Pharmacia) in 69 randomly selected control subjects; 38 ha . Immunoglobulin E (IgE) is an antibody that is produced by the body’s immune system in response to a perceived threat. It is one of five classes of immunoglobulins (A, G, M, D, and E) and is normally present in the blood in very small amounts. This test measures the amount of IgE in the blood. Immunoglobulins are proteins that play a key role in the body's immune system.
IGE: Immunoglobulin E (IgE) is one of the 5 classes of immunoglobulins and is defined by the presence of the epsilon heavy chain. It is the most recently described immunoglobulin, having first been identified in IgE exists as a monomer and is present in circulation at very low concentrations, approximately fold lower than that of IgG.
