NCT03514303

Brief Summary

The purpose of this study is to evaluate the potential correlation of the results of allergen-specific skin prick tests (SPT) to that of allergen-specific microarray determination (microassay test). Subjects who meet enrollment criteria, after signing an IRB approved consent form, will perform a minor finger prick blood draw and blot to be mailed off for microassay analysis. Specific statistical analysis will be done to assess all potential correlations between SPT and microassay. This study design should enable assessment of the level of correlation between SPT results and microassay results for specified allergens within a cohort of subjects with allergic rhinitis.
