This section deals with clinical conditions associated with allergy and hypersensitivity which are covered by the Immunology department. For each clinical condition, the relevant immunological tests are listed together with a short explanation of their use.

Allergy tests may help identify which allergens suggested by the history could cause symptoms. However, the finding of allergy specific IgE in the serum does not mean that the allergen is responsible for the symptoms under investigation, nor does it necessarily indicate that avoidance measures will help the patient.

Specific IgE provides similar, although not identical, information to skin testing but is particularly valuable in assessing some groups of patients (young children, eczema/dermographism, taking antihistamines, past history of anaphylaxis), is needed to interpret the significance of the specific IgE.

Requests for "RAST" are not acceptable.

Requests should be for specific allergens as indicated by the history.
