World's largest study reveals new model to rule out penicillin allergy

MedicalXpress | 四月 02, 2026

Melbourne researchers have led the world's largest study confirming most patients labeled allergic to penicillin are not truly allergic. The study, described as a "game changer" by lead author Professor Jason Trubiano, demonstrates for the first time that penicillin allergy testing can be safely delivered at scale as part of routine hospital care worldwide. About 1 in 10 hospital patients are recorded as having an allergy to penicillin, limiting their options for antibiotic treatments.
