    Health care providers often need to evaluate allergic disorders such as allergic rhinoconjunctivitis, asthma, and allergies to foods, drugs, latex, and venom, both in the hospital and in the clinic.

    Unfortunately, some symptoms, such as chronic nasal symptoms, can occur in both allergic and nonallergic disorders, and this overlap can confound the diagnosis and therapy.

    Blood tests are now available that measure immunoglobulin E IgE directed against specific antigens. These in vitro tests can be important tools in assessing a patient whose history suggests an allergic disease.

    In susceptible people, IgE is produced by B cells in response to specific antigens such as foods, pollens, latex, levelss drugs.

    This antigen-specific or allergen-specific IgE circulates in the serum and binds to high-affinity IgE receptors on immune effector cells such as mast cells located throughout the body.

    Upon subsequent exposure to the same allergen, IgE receptors s and initiate downstream signaling events that trigger mast cell degranulation and an immediate allergic response—hence the term immediate or Gell-Coombs type I hypersensitivity.

    Common manifestations of type I hypersensitivity reactions include signs and symptoms that can be:. The blood tests for allergic disease are immunoassays that measure the level of IgE specific to a particular allergen. The tests can be used to evaluate sensitivity to various allergens, for example, to common inhalants such as dust mites and pollens and to foods, drugs, venom, and latex.

    At present, most commercial laboratories use one of three autoanalyzer systems to measure specific IgE:. These systems use a solid-phase polymer cellulose or avidin in which the antigen is embedded.

    Apr 15,  · A blood allergy test too can help confirm a specific environmental allergy to help figure out why there is an elevated IgE level. An elevated IgE level can also represent a food allergy, the most common food allergies are wheat, milk, soy, eggs, tree nuts, peanuts, shellfish and fish. Immunoglobulin E (IgE) is a type of antibody (or immunoglobulin (Ig) "isotype") that has only been found 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 4 Ig-like constant domains (Cε1-Cε4). The predictive values for likelihood of an allergy being present differ with every food, but in general, the higher the level, the more likely that an IgE mediated allergy is present. This is also a very poor screening test due to the high rates of falsely elevated and meaningless results.

    If you get a blood test and allergy shows that you have an elevated IgE that could mean you are an allergic patient. A total elevated IgE just tells you that you have a high chance of allergies, but it does not tell you specifically what you levels allergic to.

    Your doctor may then send you for specific IgE testing. This allergg be done as an allergy skin test by an allergy doctor, where the allergist will prick your skin with different levels triggers, such as tree pollen, grass pollen and weed pollen. Or with indoor triggers such as dust mites, cat, dog or mold this can be outdoor or indoor.
