The Association of Race/Ethnicity and Patch Test Results: North American Contact Dermatitis Group, 1998-2006.

Background: The North American Contact Dermatitis Group patch tests patients with suspected allergic contact dermatitis (ACD) to a broad series of screening allergens and publishes periodic reports. We have previously reported on the association of race and ethnicity with the rates of positive responses to standard patch test allergens. This report extends those observations.
