NCT01667055

Brief Summary

The true prevalence of drug allergy in patients with a history of beta-lactam hypersensitivity will be determined by using commercially available standard skin test reagents and the diagnostic agents available in Thailand. We hypothesize that only minority of patients with such a history are truly allergic.
