RT Journal A1 Lim C, Lim S T1 NEw contrast stain for the rapid diagnosis of onychomycosis JF Archives of Dermatology JO Archives of Dermatology YR 2011 FD August 1 VO 147 IS 8 SP 981 OP 982 DO 10.1001/archdermatol.2011.208 UL http://dx.doi.org/10.1001/archdermatol.2011.208 AB Rapid confirmation of onychomycosis is desirable to differentiate it from nonfungal causes of nail dystrophy and to initiate appropriate therapy. In this study, we compared the performance of Chicago Sky Blue (CSB) stain with that of routine potassium hydroxide (KOH) preparation, using culture as the standard, in the diagnosis of onychomycosis.
