Immunoglobulin E (IgE) is a type of antibody (or immunoglobulin (Ig) "isoform") that has been found only in mammals. IgE is synthesised by plasma cells. Monomers of IgE consist of two heavy chains (ε chain) and two light chains, with the ε chain containing four Ig-like constant domains (Cε1–Cε4). [1]
An IgE level greater than 2,000 IU/mL is often considered diagnostic. [17] However, patients younger than 6 months of age may have very low to non-detectable IgE levels. Eosinophilia is also a common finding with greater than 90% of patients having eosinophil elevations greater than two standard deviations above the normal mean. [18]
Atopy is the tendency to produce an exaggerated immunoglobulin E (IgE) immune response to otherwise harmless substances in the environment. [2] Allergic diseases are clinical manifestations of such inappropriate, atopic responses.

In technical terms, an allergen is an antigen that is capable of stimulating a type-I hypersensitivity reaction in atopic individuals through immunoglobulin E (IgE) responses. [1] Most humans mount significant Immunoglobulin E responses only as a defense against parasitic infections. However, some individuals may respond to many common ...
Immunoglobulin E is a class of antibody (or immunoglobulin "isotype") that has only been found in mammals. It plays an important role in allergy, and is especially associated with type 1 hypersensitivity. There are receptors (FcεR) for the constant region of IgE, the Fc region, on several types of cells, including Mast cells and Basophils ...
When a person comes in contact with a specific trigger, their immune system produces antibodies called immunoglobulin E (IgE) molecules that bind to mast cells (immune cells found mainly in the skin, respiratory tract and digestive tract) and triggers the release of histamine and other chemicals that guards our immune system. [3]
Allergy blood tests are very safe since the person is not exposed to any allergens during the testing procedure. The test measures the concentration of specific IgE antibodies in the blood. Quantitative IgE test results increase the possibility of ranking how different substances may affect symptoms. A rule of thumb is that the higher the IgE ...
