Retrospective case series analysis of penicillin allergy testing in a UK specialist regional allergy clinic

Abstract

The new PPL and MDM determinants offer enhanced sensitivity when evaluating β-lactam hypersensitivity; however, there are limitations to the current testing regimens. The UK would benefit from local guidelines, which incorporate the new reagents and acknowledge the high amoxicillin prescription rate and the relatively lower specialist-to-patient ratio in this country.
