Urticaria/Angio-oedema

Clear allergic precipitants can be identified in only a small proportion of cases.  Patients may respond well to regular treatment with antihistamines.

Food Allergy

Skin-prick testing for a range of food allergens is available.  "Screening" is not appropriate, and diet and symptom diaries often help to identify suspected foods for testing.  Patients with life-threatening reactions benefit from detailed advice and individualised management plans.

Allergic Rhinitis and Asthma

Skin prick testing can help to identify significant aeroallergens in these patients, which may held in planning medical management.  Pollen desensitisation may be offered under certain circumstances: patients will only be considered if adequate medical therapy has failed, and certain other suitability criteria are fulfilled. 

Bee/Wasp Venom Allergy

Assessment of patients who have suffered severe reactions to bee or wasp stings is offered.  In some cases desensitisation immunotherapy is indicated to prevent anaphylaxis in individuals at particular risk.

Antibiotic and Anaesthetic Allergies

Suspected antibiotic allergy (especially to penicillin) is common, and can usually be circumvented by the choice of an alternative antibiotic.  In exceptional circumstances allergy testing may be appropriate.  It is often important to exclude or identify allergy to local and general anaesthetic agents, so that future routine or emergency treatment can be given safely.  A detailed history of the suspected anaesthetic reaction and the anaesthetic agents used are vital to successful assessment. Testing of serum tryptase levels immediately after an anaphylactic episode often aids diagnosis (see Laboratory Services).
