Preliminary studies of the TRUE test patch test system in the United States. TRUE Test Study Group.
Comparison of the TRUE Test patch test system with the chamber system recommended by the North American Contact Dermatitis Group showed concordance of results in 98% of tests with nickel, epoxy resin, and ethylenediamine dihydrochloride. Also, a panel of 12 TRUE Test screening allergens tested on 128 patients showed no irritant reactions but did show 46 positive responses of varying intensity. The TRUE Test is a promising alternative to current methods and offers the advantages of easy application and factory quality control.
