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.
Allergy testing can help confirm or rule out allergies and consequently reduce adverse reactions and limit unnecessary avoidance and medications. [1] [2]Correct allergy diagnosis, counseling and avoidance advice based on valid allergy test results is of utmost importance and can help reduce the incidence of symptoms, and the need for medications and improve quality of life.

A food allergy is an abnormal immune response to food.The symptoms of the allergic reaction may range from mild to severe. They may include itchiness, swelling of the tongue, vomiting, diarrhea, hives, trouble breathing, or low blood pressure.
Cross-reactive carbohydrate determinants (CCDs) play a role in the context of allergy diagnosis.The terms CCD or CCDs describe protein-linked carbohydrate structures responsible for the phenomenon of cross-reactivity of sera from allergic patients towards a wide range of allergens from plants and insects.
A test panel is a predetermined group of medical tests used in the diagnosis and treatment of disease.. Test panels (sometimes called profiles) are typically composed of individual laboratory tests which are related in some way: by the medical condition they are intended to help diagnose (cardiac risk panel), by the specimen type (complete blood count, CBC), by the tests most frequently ...

This is in contrast to a type-I allergy, which is mediated by IgE antibodies and is often tested using an ELISA test. In genetically predisposed individuals, an ongoing exposure to allergens can induce type-IV hypersensitivity. [citation needed] The MELISA assay is a cell culture and requires live memory lymphocytes. Lymphocytes are isolated ...
