Evaluating the usefulness of retesting for beta-lactam allergy in children.
Many children with adverse reactions to beta-lactams are labeled as allergic without performing an allergy study to confirm it. In this retrospective study of 10 years, we detected only 3.3% positive cases. Although international guidelines recommend a second allergy workup in patients with a negative study, we found from our results a low profitability of retesting.
