Hymenoptera venom allergy: taking the sting out of difficult cases.

Abstract

In about half the patients with diagnosis of venom allergy, unequivocal specific IgE and VST results are obtained and additional tests are not needed. In the remainder, diagnosis is less straightforward due to discrepant or negative specific IgE orVST results. In these patients, BAT constitutes a helpful additional instrument to identify the culprit venom and start venom immunotherapy accordingly.
