Allergy Testing

Blood testing for allergies at Greenfields
Allergy testing is different to food intolerance testing: allergies are an immediate hypersensitivity reaction, and are triggered by IgE antibodies, whereas food intolerance is a delayed hypersensitivity reaction, and is triggered by IgG antibodies. The consequence is likely to be skin inflammation, breathing difficulties, and other immediate effects from allergy exposure.

Individual allergens can be tested, or a panel of allergens, such as inhalants (for hay fever, dust, animal dander, molds), or foods. Specific foods such as nuts and seeds or shellfish can be tested in a separate panel. Antibiotics can be tested to ensure that antimicrobial medical treatment is appropriate. Profiles for eczema, rhinitis and urticaria will test for the triggers most likely to cause a reaction.

A total IgE blood test is recommended initially, to establish the total level of allergic antibodies in the blood. If this is low, the problem is unlikely to be an allergy, and would be more appropriately tested using a different type of testing, such as histamine levels or gluten intolerance.

A case history taken at your first appointment will help to find out the most appropriate type of test for allergic-type symptoms.
