The proportion of additional sensitizations detected through serum-specific immunoglobulin E (ssIgE) and intradermal skin prick testing (IDST) when skin-prick testing (SPT) results were negative, through SPT and IDST (done in cases of negative SPT results) when ssIgE levels were negative, and through ssIgE testing when IDST (done in cases of negative SPT results) were negative.
