What's being measured
Primary outcomes are the specific endpoints the trial is designed to prove or disprove.
-
Prevalence of Penicillin allergy in the studied group
Time frame: up to 4 years
Frequency of true penicillin allergy in the study group -
Negative predictive value of the allergy work- up
Time frame: 3 weeks
If the allergy work-up is negative, drug provocation test with penicillin will be performed. The purpose of the drug challenge is to confirm lack of allergy and confirm the negative predictive value of the allergy work-up.
Sponsor's own description
The purpose of this study is to estimate the prevalence of penicillin allergy, evaluate the diagnostic value of the allergologic work-up used in the study, and the health effects of penicillin allergy.
