How Does Radioallergosorbent Testing Work?

RAST works by measuring the levels of IgE antibodies, which are associated with immediate allergic reactions. This method utilizes radioactive or enzyme-linked markers to identify specific IgE antibodies bound to allergenic proteins. By assessing the presence and quantity of IgE antibodies, RAST can identify potential allergens causing immediate allergic responses.

Immediate allergic reactions, also known as type I hypersensitivity reactions, occur within minutes to hours after exposure to an allergen. These reactions are mediated by IgE antibodies, which are produced by the immune system in response to specific allergens. IgE antibodies bind to allergenic proteins and trigger the release of histamine and other chemicals, leading to the characteristic symptoms of an allergic reaction.

Radioallergosorbent Testing (RAST) is a laboratory technique that enables the measurement of IgE antibodies in the blood. This test involves exposing a blood sample to various allergenic proteins and then detecting the presence of IgE antibodies that bind to these proteins. RAST can utilize either radioactive or enzyme-linked markers to identify the IgE antibodies, allowing for accurate and precise measurements.

By identifying the specific IgE antibodies present in an individual's blood, RAST can help determine which allergenic proteins are triggering their immediate allergic reactions. This information is crucial for managing allergies and avoiding exposure to potential allergens that can cause severe symptoms.

Both the 96 General Food Panel: IgG4 by US BioTek and RAST play important roles in food allergy testing. While the former focuses on delayed immune responses mediated by IgG4 antibodies, the latter targets immediate allergic reactions mediated by IgE antibodies.
