CRD was performed with the ImmunoCAP ISAC microarray and traditional singleplexed ImmunoCAP.<\/jats:p><jats:p><jats:bold>Results\n\t\t\t\t\t<\/jats:bold> In all patients, the diagnosis of latex allergy could be established by the combination of recombinant latex components present on the microarray (Hev b 1, Hev b 3, Hev b 5 and Hev b 6.02). Over three\u2010quarters of our patients were sensitized for Hev b 5 and\/or Hev b 6.02. Some patients also displayed reactivity for Hev b 1 and\/or Hev b 3. In contrast, none of the individuals sensitized to natural rubber latex or control individuals demonstrated IgE reactivity for rHev b 1, rHev b 3, rHev b 5 or rHev b 6.02. Three\u2010quarters of the patients sensitized to latex displayed a positive microarray result for recombinant latex profilin (rHev b 8). In contrast to the results obtained by traditional ImmunoCAP for bromelain, almost no sensitization for cross\u2010reactive carbohydrates was demonstrated by bromelain spotted on the microarray. CRD by traditional singleplexed ImmunoCAP showed highly comparable results.<\/jats:p><jats:p><jats:bold>Conclusion\n\t\t\t\t\t<\/jats:bold> CRD by microarray is a reliable tool for diagnosing latex allergy. In addition, the technique allows discrimination between genuine allergy and sensitization. CRD by microarray can improve the diagnosis of IgE\u2010mediated latex allergy by discriminating between genuine allergy and sensitization. CRD by microarray is a reliable tool to diagnose latex allergy. In addition, the technique allows discrimination between a genuine allergy and simple sensitization.<\/jats:p><jats:p> <jats:italic>Cite this as<\/jats:italic>: D. G. Ebo, M. M. Hagendorens, K. J.
