The presence of significant levels of specific IgE antibodies to defined allergens in conjunction with a relevant clinical history is suggestive of IgE mediated allergy .

Allergy testing measures the amount of IgE (allergy) antibodies in your blood. IgE antibodies are produced when your body reacts to substances that you might be allergic to, such as specific foods. A variety of methods is available for allergen-specific IgE tests.

symtom; Riskfaktorer för en Blod- eller RAST-test : Detta test mäter mängden av immunoglobin E (IgE) Den första kommersiellt tillgängliga metoden för att påvisa allergenspecifika IgE-antikroppar kallades Radio-allergo-sorbent-test, förkortat RAST. Fortfarande Allergidiagnostik. Från mitten av 1970-talet accepterades allmänt pricktesten istället för intrakutantest för diagnostik av allergi.

Allergy IgE testing ImmunoCap measures free specific IgE to an individual allergens that you and your allergy consultant suspect to be related to your symptoms. This allergy blood test can be done for more than 400 different allergens (developed by our partner – Phadia – division of Thermo Fisher scientific).

A RAST (Radioallergosorbent test) is a way of measuring the amount of IgE antibody in the blood stream made against a specific allergen. RAST tests and allergy skin tests give similar information. Both identify IgE antibody (allergy antibody) against materials you might be allergic to.

Couple this with an examination and specific allergy testing, and you should have a complete allergy diagnosis. Skin prick tests or blood (RAST or ssIgE) tests can be performed to help diagnose allergies – either by observing reactions on the skin or by measuring the amount of IgE antibody produced to a specific allergen in the blood.

While the traditional method for blood testing was the RAST (radioallergosorbent test), it has been largely replaced with newer IgE-specific immunoassay methods. Routine measurement of circulating allergen specific IgE antibodies in patient sera was initially accomplished using Radio-Allergo-Sorbent Tests (RAST), which ELISA (enzyme-linked immunosorbent assay) is another in vitro method of allergy testing for specific IgE antibodies against allergens.
