Compilation of international standards for patch testing methodology and allergens.
BACKGROUND
Recommendations for patch testing methodology and allergens differ between contact dermatitis groups worldwide. Currently, there is no compilation of these recommendations.


OBJECTIVE
This study aims to summarize the current recommendations for patch testing methodology and allergens.


METHODS
Data was collected through a literature search and by contacting representatives from 24 known contact dermatitis groups.


RESULTS
Thirteen groups responded to our inquiry. As expected, recommendations for allergens and methodology varied between different groups; however, most groups based their recommendations on the European baseline series. We have compiled tables of methodologies and commonly tested allergens.


CONCLUSIONS
The differences between groups underscore the need for further international collaboration among contact dermatitis groups.
