Nail sampling in onychomycosis: comparative study of curettage from three sites of the infected nail

Background: Onychomycosis is a common problem.Obtaining accurate laboratory test results before treatment is important in clinical practice since the treatment of onychomycosis requires expensive oral antifungal therapy with potentially serious side‐effects. The purpose of this study was to compare results of curettage technique of nail sampling in the diagnosis of onychomycosis from three different sites of the affected nail to establish the best location of sampling.
