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 ]
Another laboratory test is the blood test for IgE (immunoglobulin production), such as the radioallergosorbent test (RAST) or the more recent enzyme allergosorbent tests (EAST), implemented to detect high levels of allergen-specific IgE in response to particular allergens. Although blood tests are less accurate than the skin tests, they can be ...
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 ]
A major breakthrough in understanding the mechanisms of allergy was the discovery of the antibody class labeled immunoglobulin E (IgE). IgE was simultaneously discovered in 1966–67 by two independent groups: [ 167 ] Ishizaka 's team at the Children's Asthma Research Institute and Hospital in Denver, USA, [ 168 ] and by Gunnar Johansson and ...
While true allergies are associated with fast-acting immunoglobulin IgE responses, it can be difficult to determine the offending food causing a food intolerance because the response generally takes place over a prolonged period of time. Thus, the causative agent and the response are separated in time, and may not be obviously related.
