A critical analysis of the utility of component tests in the diagnosis of pollen-related peanut and hazelnut allergy in the context of the BSACI guideline

Abstract

We congratulate the authors for producing a comprehensive guideline on the diagnosis and management of peanut and tree nut allergy(1) This is likely to improve care via standardisation across the UK NHS Allergy services.

Several studies have illustrated the benefit of component resolved diagnostic (CRD) testing by enhancing the accuracy of peanut and hazelnut allergy diagnosis and aiding the process of risk stratification. However, most of these data are derived from studies carried out on children in Europe and USA with little evidence from adults and the British population.
