Food allergy testing
If you suspect that you or someone you know has a food allergy it is a good idea to be tested to make sure and to find out how bad you may react to the food allergen.
Food allergy testing is usually done by an allergist, who will perform skin prick tests and blood tests.
* Skin prick tests introduce a tiny amount of different possible allergy causing substances to the skin and they look for a skin reaction such as swelling or itching. While the skin prick test can determine if the body will have a reaction to a certain type of food allergen, it cannot predict what reaction might happen if a person ingests that food allergen.
* In blood tests, the level of IgE antibodies is measured. There are certain average levels of accepted IgE levels for certain foods and if they are higher than that then a person is considered to have a food allergy.
