Immunoglobulin E (IgE) is an antibody that is produced by the body’s immune system in response to a perceived threat. This 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 analyses the amount of IgE in the blood.
It is recommended:In the case of symptoms of allergies.In case of doubt of parasitic infection. To analyse the children's having a family history of allergies. To check in case of suspected allergic respiratory disease. To confirm sensitivity to the foods in patients with asthma, angioedema, or cutaneous disease. To evaluate sensitivity to insect venom allergens.
The Immunoglobulin E Total (IgE - Total) test measures:The amount of IgE (immunoglobulin E) in the blood. It is an antibody that is produced by the immune system in response to danger.Normally, it is present in very small levels in the blood. This belongs to the classes of immunoglobulins, which include five types of immunoglobulins: IgA, IgG, IgM, IgD, and IgE.The total IgE test, also known as the quantitative IgE test, analyses the quantity of immunoglobulin E (IgE) in the blood.The production of IgE is seen in the cases of responses to allergens such as asthma and parasitic infections. Other allergens can include plant pollen, eggs, peanuts, bee venom, strawberries, and other allergenic substances.These IgE antibodies, once they are produced, bind with white blood cells and lead to the release of substances like histamine. This further causes constriction of the bronchi in the lungs in allergic or asthmatic people.
