Abstract

Background:: Patch testing is an important part of diagnosing allergic contact dermatitis although there is much variability in methodology among practitioners.

Objective:: We surveyed members of the American Contact Dermatitis Society (ACDS) to quantify time spent with patients with contact dermatitis; to characterize patch testing practices, including the Thin‐Layer Rapid Use Epicutaneous (T.R.U.E.) Test; and to assess utilization of the Contact Allergen Replacement Database (CARD).

Methods:: An electronic survey was sent to all members of the ACDS.

Results:: Our survey was sent to the 600 members of the ACDS; 100 members participated (a response rate of 16.6%). Respondents used patch testing trays that contained an average of 62 allergens; 68% of respondents used the North American Contact Dermatitis Group series, and only 9% used the T.R.U.E. Test. Respondents' biggest criticism of the T.R.U.E. Test was its low number of allergens, and 94% of respondents used CARD regularly.

Conclusion:: ACDS members used patch testing trays with many allergens. Despite the T.R.U.E. Test's popularity among general dermatologists and allergists, few ACDS members used it. Routine CARD usage should be encouraged.
