Antibiotic allergy testing
Disease Information
Overview
As many as 10 percent of children are allergic to antibiotics. If your child has had an allergic reaction to an antibiotic, a doctor may advise an allergy test for antibiotics.
Skin testing is available for penicillin. Skin testing for other antibiotics, such as cephalosporins, can be done, but the validity is uncertain. Routine skin testing for sulfa drugs (found in Bactrim or Septra), erythromycin or clindamycin isn’t currently available.
