Excipient and Dose per Unit Area Affect Sensitivity When Patch Testing with Gold Sodium Thiosulfate
Background Dose/area and reading paradigms for gold patch testing are controversial and not standardized worldwide. Objectives The aims of this study were to determine the optimum patch test dose of gold sodium thiosulfate (GST) in a hydrogel (HYD) and to establish GST HYD safety/efficacy and further characterize normal morphology and time course of GST reactions. Methods Twenty gold-allergic pati
