Feature Article Immunology and allergy
Investigating the atopic child
Abstract
Each case of allergy should be considered on its merits – not all will need allergy testing. This article discusses the tests available for investigating allergic reactions, and indicates when patients should be referred to allergy or immunology specialists.
Key Points
- The prevalence of allergic disorders is increasing rapidly.
- Testing for specific IgE-mediated hypersensivity is indicated in those clinical conditions in which IgE has a role.
- The skin prick test is the gold standard for assessment of atopic sensitivities.
- The clinical significance of a positive allergy test result depends on the pretest plausibility of a causative relation.
- High risk and complex cases merit referral for specialist opinion.
