Study Summary
The goal of this study is to compare ten current and readily available FDA approved allergy skin prick devices to determine the most sensitive and specific product and methods used for the diagnosis of allergic disease. The primary outcome will be to determine the analytical sensitivity and specificity of all ten skin prick devices by measuring wheal and flare response to histamine and control diluent in 1mm increments. Secondary outcomes include comparison of skin prick technique, optimum histamine concentration, patient comfort, reproducibility, and the comparability of high-resolution digital images.
Primary Outcome
Compare Wheal response among devices using 1mm precision. SPT test will be read at 15 min time point. The maximum wheal diameter will be recorded for each of ten skin prick devices. 3mm (and 2mm above negative control) qualify as a positive test.
Interventions
- DEVICE Histamine skin testing
