A new framework for the interpretation of IgE sensitization tests (original) (raw)

Allergy, 2016

Abstract

IgE sensitization tests, such as skin prick testing and serum specific IgE, have been used to diagnose IgE-mediated clinical allergy for many years. Their prime drawback is that they detect sensitization which is only loosely related to clinical allergy. Many patients therefore require provocation tests to make a definitive diagnosis; these are often expensive and potentially associated with severe reactions. The likelihood of clinical allergy can be semi-quantified from an IgE sensitization test results. This relationship varies though according to the patients' age, ethnicity, nature of the putative allergic reaction and co-existing clinical diseases such as eczema. The likelihood of clinical allergy can be more precisely estimated from an IgE sensitization test result, by taking into account the patient's presenting features (pre-test probability). The presence of each of these patient specific factors may mean that a patient is more or less likely to have clinically alle...
