Question

Quizplus · Accepted Answer

The radioimmunosorbent assay (RIA) is a type of immunoassay that can detect the presence of specific antigens or antibodies in a sample. It is commonly used in clinical settings to diagnose type I hypersensitivity reactions, such as allergies. In a RIA for allergies, a small amount of allergen is mixed with a person's blood sample and allowed to bind with specific IgE antibodies present in the sample. The mixture is then exposed to a radioactive or enzyme-labeled anti-IgE antibody. If the original sample contained IgE antibodies, the anti-IgE antibody will bind to the IgE-allergen complex, which can then be measured by the amount of radioactivity or color change produced by the enzyme. Therefore, the RIA is a useful tool for diagnosing type I hypersensitivity reactions.
