Table 2 Number of food and aeroallergen sensitizations by participant based on the type of test performed

From: Pilot study: assessing the clinical diagnosis of allergy in atopic children using a microarray assay in addition to skin prick testing and serum specific IgE

Number of sensitizations SPT (%) Specific IgE (%) ISAC (%) P value

  1. P values represent Chi square test. Given that this was significant for aeroallergens (*), pairwise comparisons were undertaken for aeroallergen sensitization: SPT vs. specific IgE (p = 0.201), specific IgE vs. ISAC (p = 0.023), SPT vs. ISAC (p = 0.119)
