Allergy and Immunology Testing

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. When combined with a clinical history, allergy test results enable doctors to recommend suitable treatment and management options. These include medications, allergen immunotherapy (desensitisation) and allergen avoidance advice.

Oral allergen challenge testing to foods or drug (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 and costly treatments, and harmful dietary restrictions.
