Allergy testing is used to identify or confirm what allergens are causing allergy and/or asthma symptoms, using skin prick tests or blood tests measure allergen specific Immunoglobulin E (IgE) antibodies. Allergy test results allow doctors to recommend suitable treatment and management options, including allergen immunotherapy and allergen avoidance advice.
Oral allergen challenge testing to foods or drugs (medications) is sometimes required when the cause of a severe allergic reaction (anaphylaxis) has not been confirmed. This is usually performed under the supervision of a clinical immunology/allergy specialist, with immediate access to emergency equipment.
Methods that are not evidence based but claim to test for allergy are unproven and not recommended by ASCIA. These tests can result in misdiagnosis, ineffective treatments, costly and often dangerous dietary restrictions.
