Order IgE Test | Immunoglobulin E Level TestingThe IgE Test measures the total amount of immunoglobulin E (IgE) in the blood. IgE is an antibody class that plays a central role in allergic responses. This test provides a quantitative assessment of total IgE levels, which can be useful in the evaluation of allergic diseases.
About IgE Test | Immunoglobulin E Level Testing in Pasadena
Total IgE testing is a broad screening tool for allergic conditions.
Immunoglobulin E (IgE) is one of the five major classes of antibodies produced by the immune system. It is found in very low concentrations in the blood of most individuals. IgE binds to receptors on mast cells and basophils, and when it encounters specific allergens, it triggers the release of histamine and other inflammatory mediators. This process underlies many allergic symptoms, such as sneezing, itching, and bronchoconstriction.
The total IgE test quantifies the overall level of IgE in the bloodstream, without identifying which specific allergens may be responsible. Elevated total IgE levels can be seen in various allergic conditions, including allergic rhinitis, asthma, atopic dermatitis, and parasitic infections. However, total IgE levels can also be influenced by age, genetics, and environmental exposures, and not all individuals with allergies have elevated total IgE.
Because total IgE testing does not pinpoint specific allergens, it is often used as an initial screen. If results are elevated, healthcare providers may order allergen-specific IgE tests to identify particular triggers. The test requires a simple blood draw and is typically performed in a clinical laboratory. Results are reported as international units per milliliter (IU/mL).
