Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test. 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 1966.he function of IgE is also distinct from other immunoglobulins in that it induces activation of mast cells and basophils through the cell-surface receptor Fc epsilon RI. Fc epsilon RI is a high-affinity receptor specific for IgE present at a high density on tissue-resident mast cells and basophils.
