(a) Comparative sensitization rates detected by SPT and ImmunoCAP Blot across allergic cohorts (N = 329). The bar graph illustrates the percentage of individuals testing positive for each allergen using two diagnostic methods: SPT Blot (light blue) and ImmunoCAP Blot (dark blue). Data represent only positive cases, highlighting differential detection rates and potential variability in allergen recognition between skin prick testing and in vitro IgE measurement. (b) Distribution of population response to Blomia tropicalis based on concordance and discordance between SPT and ImmunoCAP results. “Concordant” refers to individuals with matching test outcomes (both positive or both negative). “Discordant (SPT⁺/ImmunoCAP⁻)” and “Discordant (SPT⁻/ImmunoCAP⁺)” represent individuals with conflicting test results. Percentages are calculated relative to each diagnostic subgroup and are not additive across categories. This visualization highlights test agreement and discrepancy patterns rather than cumulative population proportions.
