title: "In vivo" and "in vitro" tests in the diagnosis of Beta-lactams allergy.
abstract: The results of "in vivo" and "in vitro" diagnostic tests in 114 patients reporting an allergic reaction to Beta-lactams are presented. Skin test gave an overall positivity of 85% and determination of specific IgE of 42%. Skin tests have a greater sensitivity but "in vitro" tests are an useful associated diagnostic method.
