It is desirable to further evaluate the clinical relevance of a positive patch test. The repeated open application test (ROAT) has been suggested as such a supplementary method. To compare the results of patch testing with the outcome of ROATs;13 colophony-sensitive subjects and 9 controls were patch-tested with colophony in a serial dilution test. Five microliters;of three concentrations of a colophony solution and the vehicle were then applied to small test areas on the lower arm;once daily for 2 weeks. Prior to each application;all test sites were examined visually and with bioengineering techniques. In the ROATs;10/13 colophony-sensitive subjects--but no controls--reacted to a 20% colophonyDownloads
