    The RAST is a radioimmunoassay test to detect specific IgE antibodies to suspected or known allergens for the purpose of guiding a diagnosis about allergy. [10] [11] IgE is the antibody associated with Type I allergic response: for example, if a person exhibits a high level of IgE directed against pollen, the test may indicate the person is allergic to pollen (or pollen-like) proteins.

    en.wikipedia.org/wiki/Radial_immunodiffusion

    A solution containing antibody is added to a heated medium such as agar or agarose dissolved in buffered normal saline.The molten medium is then poured onto a microscope slide or into an open container, such as a Petri dish, and allowed to cool and form a gel.

  4. Allergy test - Wikipedia

    en.wikipedia.org/wiki/Allergy_test

    Allergy blood tests measure the presence of IgE antibodies to specific foods, pollens, mites, animals, insects and other environmental factors. (IgE, short for "immunoglobulin E", is the antibody that triggers food allergy symptoms.) The doctor looks at the test results to help determine if the patient has allergies.

    en.wikipedia.org/wiki/Radioimmunoassay

    A radioimmunoassay (RIA) is an immunoassay that uses radiolabeled molecules in a stepwise formation of immune complexes.A RIA is a very sensitive in vitro assay technique used to measure concentrations of substances, usually measuring antigen concentrations (for example, hormone levels in blood) by use of antibodies.

  8. Immunoradiometric assay - Wikipedia

    en.wikipedia.org/wiki/Immunoradiometric_assay

    In IRMA, the antibodies are labeled with radioisotopes which are used to bind antigens present in the specimen. When a positive sample is added to the tubes, radioactively labeled (labeled with I125 or I131 radioisotopes) antibodies bind to the free epitopes of antigens and form an antigen-antibody complex.

    A wide range of medical tests are immunoassays, called immunodiagnostics in this context. Many home pregnancy tests are immunoassays, which detect the pregnancy marker human chorionic gonadotropin. [20] More specifically, they are qualitative tests that detect whether hCG is present, using a lateral flow setup. [21]
