Your allergist will recommend that you have an allergy blood test to measure the amount of IgE (allergy) antibodies in your blood. When your body reacts to substances that you might be allergic to, such as specific foods or chemicals, IgE antibodies are produced, so this acts as a marker against your potential allergy.
To find out what is causing an allergic reaction, your blood can be taken to the laboratory and tested against common allergens. The severity of your allergic response is usually due to a combination of the extent of your exposure to allergens and genetic background.
